Monarch Population Status

The WWF-Telmex Telcel Foundation Alliance, in collaboration with the National Commission of Natural Protected Areas (CONANP), the National Autonomous University of Mexico (UNAM), and the Monarch Butterfly Biosphere Reserve (MBBR), announced the total forest area occupied by overwintering monarch colonies today. Eleven (11) colonies were located this winter season with a total area of 2.21 hectares, a 22% decrease from the previous season (2.84 ha):

WWF story: Troubling news for monarch butterfly populations

Monarch population growth is largely about timing, numbers and weather. Monarch Watch follows the population closely from month to month throughout the year looking for changes that will help us predict the relative size of the population from one interval or stage to the next. This year, starting in May, the data indicated that the mid and late summer numbers would be low and that the migration itself would involve a smaller population than in recent years. This expectation was realized. The number of butterflies tagged during the migration was the lowest in 9 years. This was another sign that the overwintering numbers would be low since the number tagged is correlated with the size of the overwintering population. Two other factors, droughts in Texas and late arrival at the overwintering sites, are associated with low numbers and both occurred last fall.

All in all, monarchs had a bad year due to a sequence of unfavorable weather events. While low numbers are something of a concern, in recent years monarchs recovered from low numbers in 2012 (1.19 ha), 2013 (0.67 ha) and 2014 (1.13 ha) and they will do so again – weather permitting. For more information on the status of the population through the last season see monarchwatch.org/blog/2023/01/04/monarch-population-status-49

Note:
The WWF-TELMEX Telcel Foundation Alliance collaborates with CONANP to systematically monitor the hibernation of the Monarch since 2004, and they join the Institute of Biology of the National Autonomous University of Mexico (UNAM) to analyze changes in forest cover in the area core of the Monarch Butterfly Biosphere Reserve in order to have scientific bases that support the implementation of conservation strategies for the benefit of the species, ecosystems and human beings.

2. Overwintering Monarchs at El Rosario

The days are getting longer, and temperatures are increasing in the northern hemisphere. The decline in activities imposed on nearly all insects by cold conditions is beginning to reverse. For monarchs, that means more flight typified by streaming downslope to seeps and areas where the grasses are covered by dew. They need water to metabolize the lipids acquired during the migration into a sugar named trehalose that provides the energy needed to power all bodily functions. As the temperatures increase, monarchs also become more sexually active with mating increasing dramatically after the 12th of February when the angle of the sun above the horizon at noon drops below 57 degrees. This connection with the solar angle at solar noon (SASN) may be coincidental or not, but there is a connection with both the start of the migration and its end. In the vicinity of Winnipeg at 50N, the migration begins in the first week of August when the SASN value drops below 57 degrees. Further, the first monarchs arrive in the vicinity of the overwintering sites in the last few days of October when the SASN value drops below 57. Celestial changes may also be associated with the declining increase in day length as first-generation monarchs colonize the summer breeding areas. For discussions on this topic see the “Monarch Puzzle Wrap Up” article at https://monarchwatch.org/blog/2022/04/22/monarch-puzzle-wrap-up

As to mating, a study by Tonya Von Hook (1993) indicated that mating in February was predominantly between small males, that were often in poor condition, and large females. While that raised questions about whether small males might be selecting large females as mates based on their prospective ability to lay large numbers of eggs, there are several other things that we should be thinking about. First, why is it that small males are engaging in sexual activity and larger males are less engaged in courtship behavior? Next, are the small males actually selecting for size or are they only able to mate with the larger females? Also, is there any reason large females would choose to mate with small males? And if small males are not discriminating but are attempting to mate with all females, what does that say about these dynamics? Lastly, what if there is no selection by either sex? Could that explain the outcomes?

Maybe it comes down to one word – maneuverability. The small males and females could be more maneuverable with the result that small females are more often able to escape the attentions of small males than large females. Problem solved, but what about those small males, why are they sexually active sooner than larger males? Again, one word – hormones, specifically juvenile hormone (JH) produced by a gland in the head known as the corpora alata. JH production leads to the development and maturation of reproductive tissues, and it could be that small males simply produce more of this hormone early in the season or that all males produce similar amounts, but that JH activates sexual activity faster in the small males due to their small mass and lower lipid content. Since it is possible, perhaps evenly likely, that small males wouldn’t survive the return migration to Texas, there is a tendency to attribute this behavior to a recognition on the part of these males that it’s now or never. If so, we would be talking about cognition and that would be asking a lot for an organism with a mass of less than half a gram and very small brain. So, I don’t think so. It’s just hormones.

While those activities represent what a portion of the overwintering monarchs are doing, the majority, and especially those deep within the forest, are settled on limbs and tree trunks as shown in the pictures below. These photos were taken by Estela Romero on visits to the monarch colony at El Rosario in the first week of February and last week of January 2023.

3. Monarch Watch Tag Recoveries

Many of you have been asking about when tag recoveries for the 2022 tagging season will be posted online. The tag recoveries within the U.S., Canada and northern Mexico were recently posted online via https://monarchwatch.org/tagrecoveries; recoveries from the overwintering sites in central Mexico are typically reported to us in March and posted online in April once everything is received and verified. We will make an announcement via our email updates so stay tuned!

As a reminder, if you have not submitted your tagging data to us yet, it is not too late! Complete information (including links to the tag data submission form and recovery lists) is available on our Monarch Tagging Program page at https://monarchwatch.org/tagging

4. International Western Monarch Summit

–Chip Taylor, Director, Monarch Watch, University of Kansas

There is a growing movement in the West to sustain the Western monarch population. Efforts are underway in all states west of the divide (except Montana and Wyoming) to provide data that can be used to understand why this population varies from year to year and what can be done to assure there will be monarchs in the future. These efforts are led by Robert Coffan who has been aided by a dedicated group of supporters. The first Western Summit was held in January 2020 and the second in San Luis Obispo in January 2023. I was invited to speak at both events.

In the first, I stumbled through an attempt to bring what I knew about the dynamics of the eastern population to the West. Looking back, there were both good and naïve approaches to understanding monarch numbers in the West. I did show that temperatures were increasing and that the effect was leading to a decline in overwintering locations and numbers in the five southern counties. I also created a matrix of monthly means of temperatures and precipitation for all time periods and areas of the West. Colleagues and I have worked that matrix over and over to identify patterns and explanations, but aside from the general increase in temperatures associated with declines, I consider that approach to be a failure.

In the slides linked below, I have taken a deeper dive into the differences in the conditions between the East and West. As you will see, the West is not only more complicated, but there is only one data set to work with – and there are reasons to question how well that data set represents the size of the population, especially in warmer years.

In summary, there are several messages: 1) more data are needed, 2) the year-to-year variation is largely driven by weather and not habitat loss, pesticides or other factors, and 3) in the long term, monarch numbers will be driven by increasing temperatures from September through February in the coastal counties.

You are welcome to share, discuss and question the interpretations on these slides.

5. Milkweed Programs & Milkweed Market

Monarchs Need Milkweed. Monarch caterpillars only eat milkweed, and you can get milkweed plants from Monarch Watch, possibly for free! Just choose the milkweed program that fits your situation.

Free milkweeds for habitat restoration projects

Monarch Watch will once again be distributing free milkweeds for planting in large-scale habitat restoration projects Spring 2023. Since this program began in 2015, over 731,000 milkweeds have been planted in restored habitat throughout much of the monarch breeding range. New this year, we have added several more regions in California. To qualify, applicants must have a minimum of two acres (one acre or less in California) to restore to natural, native habitat, and have a management plan in place. Milkweeds are awarded on a first come, first served basis, so apply early.

Those awarded free milkweeds need only pay shipping/handling, which is modest compared to the value of the plants. Please help us spread the word by sharing widely. For more information and to apply, please visit: https://monarchwatch.org/free-milkweed-restoration

Free milkweeds for schools and educational non-profits

Schools and educational nonprofits may apply for a free flat of native milkweeds for a public garden or habitat space. Single flats of 32 plants (58 for Texas) will be distributed to recipients in the spring, while milkweed supplies last. The application can be found here: https://monarchwatch.org/free-milkweed-schools-nonprofits

Milkweed Market

Native milkweeds for gardens or habitat are available for purchase from our Milkweed Market at https://shop.milkweedmarket.org The minimum purchase is one flat of 32 plants (58 for Texas). If your space is not large enough for 32 milkweeds, share with your neighbors! The market is now open for pre-orders and availability is based on your ZIP code and our supply.

6. Wanted: Gerber Baby Food Tubs

Reduce, Reuse, Recycle! Do you or someone you know use Gerber Baby Food that comes in those small plastic tubs? If you have access to a supply of these empty containers, consider sending them to us (please rinse them first!) for reuse as monarch rearing chambers. I don’t think Gerber had monarchs in mind when they introduced these tubs, but they work quite well and save us a lot of time compared to other methods we’ve used. The 4 oz tubs work best but we can use the 2 oz tubs as well.

Some of you may recall a similar request years ago that showed how we use these tubs – the plastic lids are no longer included but we still have a good supply of those, and they fit the current tubs.

Please start saving these empty tubs for Monarch Watch and once you have a number of them (shouldn’t take long!) please contact us at monarch@ku.edu for mailing/shipping instructions. If you can coordinate a collection from several sources to send in a single package, all the better. Thank You!

9. About This Monarch Watch List

1. Monarch Population Status – Chip Taylor

Status of the eastern monarch population (as of December 2022)

I’ve said it before, but it bears repeating. Monarch numbers each season are largely due to the timing and numbers from one stage in the annual cycle to the next. Habitat availability, which comes down to the abundance and distribution of milkweeds as well as the nearby sources of nectar, sets the upper limit for monarch numbers. More habitat means more monarchs if the temperatures and rainfall throughout the year are close to the long-term averages. However, the conditions are seldom, if ever, optimal. So, the task, for those of us developing stage specific models for wildlife, is to determine how birth rates and death rates are affected within each stage that determines the number entering the next stage.

The monarch annual cycle can be broken down into six stages: (1) overwintering from November to April, (2) migrating back to the US late February to April, (3) breeding from March to May by returning monarchs, (4) first generation recolonization of the summer breeding areas north of 40N, (5) summer breeding from May to September and (6) migration from August to December.

The area of the forests with monarchs this winter is going to be low – probably one of the all-time low numbers – close to, if not below, 1 hectare (2.47 acres). I could see that the numbers would be down this year as early as late May and nothing happened through the rest of the season to change that assessment.

So, what happened from stage to stage this year? For a complete analysis, please see the recent Monarch Population Status post via our blog at https://monarchwatch.org/blog

2. Monarch Watch One Day Fundraising Event

Monarch Watch will again be featured in the University of Kansas’ annual “One Day. One KU.” 24-hour fundraising campaign which will take place in mid-February. The event will provide an opportunity for Monarch Watchers all over the globe to come together and show their support of our program.

In the past, many of you commented that you would like more notice of this event so this is just a quick heads-up before an official announcement that will be made in the coming weeks. Stay tuned!

3. Monarch Watch 30-year celebration – Chip Taylor

In the 30 years of Monarch Watch, I have had the privilege of working with many people who have had a strong interest in monarchs, education, research, conservation, outreach, filmmaking, and more. I benefited and Monarch Watch grew as a result of these many relationships.

For our 30-year anniversary, we wanted to both celebrate our achievements and thank the many people who have supported our mission through the years. We held a three-day event in September that included a banquet, symposium, garden party and monarch tagging event. That involved a lot of planning by all four of us but especially by Jim Lovett, Ann Ryan and Dena Podrebarac. Thanks to their hard work and the invaluable assistance of the entire Kong family, the celebration exceeded our expectations.

We were joined by hundreds of visitors, representing 3 countries and 30 states/provinces. Our guests also included nine of our Monarch Conservation Specialists, past staff and students, KU colleagues, volunteers and many long-time supporters. One surprise for me was the attendance of dozens of people I didn’t know – an indication that Monarch Watch has affected more people than we are aware of.

The banquet was held at Abe and Jake’s, an event facility located adjacent to the Kansas (Kaw) River. Guests were treated to live music, good food, and excellent company. The banquet ended with three speeches by Brad Williamson, who helped me start Monarch Watch, Laurie Adams, a long-time leader of the North American Pollinator Protection Campaign and the Pollinator Partnership and lastly, myself. I did some introductions and thanked many people and institutions that have helped Monarch Watch through the years. These comments were followed by a bit of history and the announcement about the future of Monarch Watch. It was a great evening.

A monarch symposium followed the next day with about 170 attendees. There were 13 talks with some speakers connected via zoom, others with pre-recorded talks and some in attendance. There was some excellent Q and A between the audience and experts at the end of the symposium. I couldn’t imagine this all going smoothly, but it did – thanks to everyone’s cooperation and Jim’s technological and organizational skills. The symposium was recorded and the video can be found, along with other materials, at https://monarchwatch.org/symposium2022

The symposium was followed by an evening in Monarch Waystation #1 – our garden so ably maintained by the Douglas County Master Gardeners. There were several things going on in the garden including a video by Gwynedd Vetter-Drusch, the dedication of a sculpture, live music and celebratory cookies. There was even a place where people could stop by to ask me questions or just chat.

The celebration wrapped up on Saturday with a monarch tagging event at the Baker Wetlands. The weather was great and those in attendance, at least 420 including many children, collected, tagged and released over 300 monarchs. After the event, the staff, volunteers, and a few exhausted attendees, assembled under the trees at Monarch Waystation #1 for a well-deserved pizza party.

All in all, the celebration seemed to hit the right notes for the attendees and the symposium received especially high marks. For me, this event confirmed that, in spite of all the improved means of communication enabled by technology, there is nothing quite like getting together face to face.

[ Jim ] Thank you to everyone who joined us for this celebration! We’d love to see photos or video from the events – if you have some that you would like to share, please do so via any method detailed at https://monarchwatch.org/share

4. Monarch Symposium

As Chip mentioned above, Monarch Watch held a mini monarch symposium at the University of Kansas as a part of our 30-year events in September. There were 170 attendees and 13 presentations by monarch experts and enthusiasts that were in person, pre-recorded, or remote. The 10-minute presentation format we adopted for this symposium allowed us to cover a number of topics in a relatively short amount of time and the feedback from presenters and attendees alike was overwhelmingly positive. We hope to do this again.

Materials distributed at the symposium are available online at the link below, including the symposium program (which contains the planned order of presentations, complete information about the presenters and their presentations (name, affiliation, contact information, title and abstract), a list of select monarch and milkweed publications from 2022, and a brief Monarch Watch timeline) and the 2021 Monarch Research Review, organized by the Monarch Joint Venture (which provides a summary of monarch research published between September 2020 and December 2021).

Additionally, the entire symposium was recorded and the full video (3h 33m) is now online at the link below and via our YouTube channel. Video “chapters” have been defined so that you may jump to a specific presentation at any time.

5. Monarch Watch Tagging Kits for 2023

Monarch tagging continues to be an important tool to help us understand the monarch migration and annual cycle. We are now accepting PREORDERS for the 2023 fall tagging season and kits will be sent out in the fall, ahead of the migration in your area. If you would like to tag monarchs this year, please order your tags as early as possible!

Monarch Watch Tagging Kits are only shipped to areas east of the Rocky Mountains. Each tagging kit includes a set of specially manufactured monarch butterfly tags (you specify quantity), a data sheet, tagging instructions, and additional monarch / migration information. Tagging Kits start at only $15 and include your choice of 25, 50, 100, 200, or 500 tags.

Monarch Watch Tagging Kits and other materials (don’t forget a net!) are available via the Monarch Watch Shop online at https://shop.monarchwatch.org – where each purchase helps support Monarch Watch.

Complete information including datasheets and instructions are available on the Monarch Tagging Program page at https://monarchwatch.org/tagging

6. Submitting Tag Data

Many of you have submitted your recent tag data to us by mail or via our online submission form – thank you! We are still receiving data sheets and if you haven’t submitted your data yet (for 2022 or even previous years) it is not too late. Please review the “Submitting Your Tagging Data” information on the tagging program page then send us your data via the Tagging Data Submission Form.

Complete information is available at https://monarchwatch.org/tagging if you have questions about submitting your data to us and we have conveniently placed a large “Submit Your Tagging Data” button on our homepage at https://monarchwatch.org that will take you directly to the online form.

There you can upload your data sheets as an Excel or other spreadsheet file (PREFERRED; download a template file from https://monarchwatch.org/tagging ) or a PDF/image file (scan or photo).

You may also use the new Monarch Watch mobile app (available for Apple and Android devices) to record and submit data – download from your app store or visit https://monarchwatch.org/app

If you have any questions about getting your data to us, please feel free to drop Jim a line anytime via JLOVETT@KU.EDU

7. Milkweed Programs

Monarchs Need Milkweed. Monarch caterpillars only eat milkweed, and you can get milkweed plants from Monarch Watch, possibly for free! Just choose the milkweed program that fits your situation.

Free milkweeds for habitat restoration projects

Monarch Watch will once again be distributing free milkweeds for planting in large-scale habitat restoration projects Spring 2023. Since this program began in 2015, nearly 732,000 milkweeds have been planted in restored habitat throughout much of the monarch range. To qualify, applicants must have a minimum of two acres (one acre or less in California) to restore to natural, native habitat, and have a management plan in place. Milkweeds are awarded on a first come, first served basis, so apply early.

Those awarded free milkweeds need only pay shipping/handling, which is modest compared to the value of the plants. Please help us spread the word by sharing widely. For more information and to apply, please visit: https://monarchwatch.org/free-milkweed-restoration

Free milkweeds for schools and educational non-profits

If you are associated with a school or educational nonprofit and plan to plant milkweeds in a public garden space, we are taking applications for 2023. Applications will be reviewed beginning in January, and single flats (32–58 plants, depending on location and species) will be distributed to recipients in the spring, while milkweed supplies last. The application can be found here: https://monarchwatch.org/free-milkweed-schools-nonprofits

Milkweed Market

Native milkweeds for your garden or habitat may be available for purchase from our Milkweed Market (not available for all areas). The minimum purchase is one flat of plants (32–58 plants, depending on location and species). If your space is too small for a flat of milkweeds, share with your neighbors! We plan to have the Milkweed Market open for pre-orders by 1 February. https://shop.milkweedmarket.org

8. Monarch Waystations

To offset the loss of milkweeds and nectar sources we need to create, conserve, and protect monarch butterfly habitats. You can help by creating “Monarch Waystations” in home gardens, at schools, businesses, parks, zoos, nature centers, along roadsides, and on other unused plots of land. Creating a Monarch Waystation can be as simple as adding milkweeds and nectar sources to existing gardens or maintaining natural habitats with milkweeds. No effort is too small to have a positive impact.

Have you created a habitat for monarchs and other wildlife? If so, help support our conservation efforts by registering your habitat as an official Monarch Waystation today!

Monarch Waystation Program: https://monarchwatch.org/waystations

A quick online application will register your site and your habitat will be added to the online registry. You will receive a certificate bearing your name and your habitat’s ID that can be used to look up its record. You may also choose to purchase a metal sign to display in your habitat to encourage others to get involved in monarch conservation.

As of 4 January 2023, there have been 41,823 Monarch Waystation habitats registered with Monarch Watch!

You can view the complete Monarch Waystation Registry and a map of approximate locations via https://monarchwatch.org/waystations/registry

Monarch Population Status

Status of the eastern monarch population (as of December 2022)

I’ve said it before, but it bears repeating. Monarch numbers each season are largely due to the timing and numbers from one stage in the annual cycle to the next. Habitat availability, which comes down to the abundance and distribution of milkweeds as well as the nearby sources of nectar, sets the upper limit for monarch numbers. More habitat means more monarchs if the temperatures and rainfall throughout the year are close to the long-term averages. However, the conditions are seldom, if ever, optimal. So, the task, for those of us developing stage specific models for wildlife, is to determine how birth rates and death rates are affected within each stage that determines the number entering the next stage.

The monarch annual cycle can be broken down into six stages: overwintering from November to April, migrating back to the US late February to April, breeding from March to May by returning monarchs, first generation recolonization of the summer breeding areas north of 40N, summer breeding from May to September and migration from August to December.

The area of the forests with monarchs this winter is going to be low – probably one of the all-time low numbers – close to, if not below, 1 hectare (2.47 acres). I could see that the numbers would be down this year as early as late May and nothing happened through the rest of the season to change that assessment.

So, what happened from stage to stage this year? I’ll give you my interpretations with the caveat that the information available on what happened during several stages is either non-existent or inadequate.

Overwintering – November-April.
While the number of hectares of trees with monarchs at the overwintering sites has been recorded every year since 1994, there is no comprehensive understanding of the mortality that occurs each winter. It is known that colonies decline in size through the winter, but whether these declines are associated with offsite mortality or the movement of overwintering colonies is not clear. The only times mortality has been estimated for the majorities of colonies is following major catastrophic events after winter storms (2002, 2004, 2010, 2016). One might think that tag recovery rate would be a good measure of winter mortality. That is surely the case for years with strong winter storms and may apply to other years as well, but overall winter mortality does not appear to be a major determinant of population size from one year to the next.

Migrating North – February-April.
The mortality during the traverse from the overwintering sites to Texas could vary substantially from one year to another due to droughts, excessively high temperatures or a lack of nectar. Monarchs utilize two routes to reach Texas, Figure 1. One, a coastal route of about 600 miles used early in March when temperatures are moderate. This route appears to shut down when the temperatures in Tamaulipas are in the 90s and higher, which is often the case by mid-March. The second, and cooler, route follows the mountains to the north toward Ciudad Victoria and then NW toward Monterrey with a crossing into Texas that takes the monarchs through the Edwards Plateau into central Texas. This route is about 800 miles and essentially duplicates the route of most of the fall migrants. Unfortunately, there is no systematic monitoring of the conditions along these routes. So, what happens from year to year along these pathways and how those conditions impact the proportions of the returning monarchs that reach Texas is unknown.

Figure 1. Spring first sightings reported for Mexico to Journey North. These records suggest monarchs use two pathways to reach the breeding grounds in Texas and beyond.

Fortunately, there is a record of first sightings for the last 23 years thanks to the reporting to Journey North and the leadership of Elizabeth Howard and Nancy Sheehan who have managed that project. To determine if the first sightings tell us something about the timing and number of monarchs arriving from Mexico in the spring, we have compiled all the first sightings from 1March through 30 April for each year. The medians range from 13 March to 2 April and both high and low overwintering numbers followed these early and late median arrivals. The overall, mean is 22 March and the median for 2022 was 25 March.

The numbers recorded each year are also hard to interpret since the number of first sightings reported in Texas has increased over the years from 37 in 2000 to 343 in 2021. Again, there are years when low and high numbers of arrivals are followed by increases and decreases in monarch numbers. Although more digging in the data is warranted, the results suggest that the timing and number of monarchs arriving from Mexico is not a major factor in determining the numbers in most overwintering periods.

Reproduction by returning migrants – March-April.
So, if the timing and numbers of monarchs from Mexico is seldom a factor, that suggests several things. First and second, overwintering mortality is also not a driver in most years nor is the traverse from the overwintering sites to Texas. There are probably years (e.g., 2004) when one or the other or both are important, but that appears to be uncommon relative to other factors that determine end of year numbers.

The temperatures in Texas in March and April have significant impact in determining the size of the population at the end of the cycle. Of the 22 years in the record, the population increased in 10 years and decreased in 12. In 9/10 years with increases, the mean temperatures for Texas were less than +2.5F above the long-term average. The exception to this trend was 2006, a year with a mean temperature for March and April of +5.3F. The number of hectares the following winter increased from 5.92 to 6.87. The explanation for the increase appears to be due to two things: the earliest arriving cohort from Mexico (median = 13 March) and the highest temperatures for April (+5.8F above average) in the entire record from 1895 to the present. The Journey North map of first sightings for the spring of 2006 suggests that early arrival combined with egg laying concentrated in Texas and southern Oklahoma, followed by high April temperatures, led to the rapid development of the larvae and a large cohort of first-generation offspring. These offspring effectively colonized the summer breeding range north of 40N with >75% of the sightings recorded from 21 to 30 May. In contrast to the increases, the population decreased in 6/7 years in which the mean temperatures were in excess of 2.5F. The exception being 2006. For the other 6 years, other factors account for the decreases. For example, decreases followed the two coldest June-August periods (2004, 2009) and late recolonizations north of 40N account for low numbers in 2013 and 2019. The declines of 2002 and 2007, which should have been increases based on March/April temperatures, remain unexplained.

First generation colonization of the summer breeding range north of 40 North

First generation monarchs, mostly originating from eggs laid by monarchs returning from Mexico in Texas and Oklahoma, begin migrating north in the last week of April. This migration appears to continue until the difference in daylength from one day to the next drops below one minute per day at each latitude (https://monarchwatch.org/blog/2022/04/22/monarch-puzzle-wrap-up/). This result indicates that the migration northward stops progressively from south to north with the last of the migration stopping on or about 12 June at 50N.

Applying the dictum that it is timing, numbers and weather that mostly determines the number of monarchs transitioning from one stage to another produced some interesting results. We summarized all the first sighting for longitudes north of 40N latitude. I’m going to refer to the areas defined by 100-90W and 90-80W bounded by latitudes 50 to 40N. These two areas account for about 90% of the recoveries of tagged butterflies in Mexico. The interval for these first sighting is from 1 May to 9 June, a 40-day period divided into 10-day intervals. When we tallied the first sightings for the 23-year interval, two years stood out: 2012 and 2013. In 2012, 92% of the first sightings occurred from 1-20 May while in 2013 only 5% of the first sightings occurred during that interval. The numbers of sightings in 2012 was >2x the number in 2013. The expectation therefore was that the population in 2012 would increase, but it declined. The starting numbers in 2013 also resulted in a decline leading to the conclusion that arriving in the northern breeding areas too soon (2012), perhaps before milkweed is available, or too late (2013), resulting in a delay in starting the summer breeding, can both result in a decline in the size of the migration and the overwintering population. Looking at these two extremes, it seemed appropriate to ask whether there is an optimal time of arrival in the northern breeding areas. Perhaps there is, but that is not evident in the data. There are at least two complications: the phenology of the milkweeds and nectar sources varies from year to year, and the weather after arrival can have a strong impact on the outcome. That’s what happened this year. Fifty-four percent of the first sightings were recorded from 1-20 May, and the numbers were good. Most of the monarchs were sighted during a warm period from 8-20 May. Cold weather followed for 4-7 days over a broad area during which the temperatures were too low most days for egg laying, mating or foraging for nectar. Once I became aware of that, I knew the population would be lower at the end of the season. Populations grow best when egg laying is not interrupted. Delays result in attrition of adults and the ability to continue producing eggs declines with age.

In putting this summary together, I looked for other factors that could explain why the numbers in the migration were low. Although there were a number of complaints of high temperatures and drought conditions from a number of places in the Midwest, scans of the temperatures and rainfall amounts failed to confirm either were extreme. Nor were there other explanations for the low numbers. So, the best I can offer is the likelihood that the interrupted reproduction in the 4th week of May accounts for the low migration and what seems certain to be a low overwintering population.

The Fall Migration – a traverse from 50N to 19.5N beginning in early August and ending in early December.

To assess the success of each migration, I try to determine the lateness of the migration, the numbers tagged, the number and sizes of the roosts reported to Journey North and whether there are drought conditions along the route. I also monitor weather conditions since extremes determine migratory success.

Monarchs tagged late in the season have a much lower chance of reaching the overwintering sites than those tagged early. The same applies to entire migrations. Migrations can be delayed by extremely high or low temperatures, strong headwinds and delayed development of the last generation due to late arrival of monarchs colonizing the breeding areas in May and June.

We also know that the numbers tagged is correlated with the size of the overwintering population. The number of roosting sites and estimates of the numbers per roost can also be useful. Extreme high or low numbers are informative, but intermediate numbers may or may not predict overwintering numbers. We also know that droughts contribute significantly to monarch mortality.

We will have to wait until the tagging data is analyzed to determine if there was more late tagging than usual this year, but that seems unlikely given how the season progressed during June through August. Also, although the temperatures were higher than the long-term averages during September in the Midwest Region and October in the South Region, there are no indications the migration was substantially delayed by the weather.

The temperatures in the vicinity of the overwintering colonies for the last 4 days of Oct, a period during which monarchs are usually spotted in the area, were quite cold and evidently delayed the arrival of the leading monarchs. However, some monarchs appeared near El Rosario on the first of November just in time for the Day of the Dead on the following day. Monarchs were slow to form clusters through November and remained quite scattered in the El Rosario area until late in the month. Whether this scattering will affect the measurements of colonies in early December remains to be seen.

The numbers tagged from 1 August to the end of the season and submitted by 30 November 2022 were only 64% of the number tagged in 2021 (54K/91K), Table 1. This figure could change as more data are received, but since numbers tagged are correlated with overwintering numbers, this result suggests that overwintering numbers will be substantially lower than those of the previous 4 years.

Table 1. A summary of the number of monarchs tagged from 1 August to the end of the season for records submitted by 30 November.

The number of temporary roosts reported to Journey North was also the lowest of the last 5 years, again suggesting lower numbers this winter, Table 2. Although roost numbers and colony numbers appear to be correlated p=0.01, a deeper dive into these data that eliminates roosts west of the continental divide and Mexico, as well as the roosts with single butterflies, or an analysis of roosts by latitude and longitude could produce different results. The numbers per roost could also affect the interpretation.

Table 2. Fall roosts as reported to Journey North, (maps.journeynorth.org/map/?map=monarch-roost-fall&year=2022).

Droughts, such as those of 2000 and 2011 that limit the amount of flowering and therefore nectar available to migrating monarchs, can have a significant impact on the number reaching the overwintering sites. There were areas of exceptional drought in portions of southern Kansas, Oklahoma and Texas and severe drought much of the migratory route in northern Mexico, Figure 1. How successful monarchs were in locating nectar under these conditions has yet to be determined, but all past measures of greenness suggest that the conditions this fall probably limited the number of monarchs reaching the overwintering sites.

The above is my rationale for saying at the outset that the area occupied by overwintering monarchs would be close to, if not below, 1 hectare (2.47 acres). As always, these predictions are a test of the value of the metrics and/or how they are applied to the question. This stage-specific approach reveals massive data gaps and shows us how little we know about monarch demography. This approach also allows us to see that not everything is linear. There are many optima to consider (see Why monarchs are an enzyme). For example, populations decline if the growing season temperatures are too high or too low and grow substantially when the temperatures are close to the long-term average. Arriving early in breeding grounds can get the population off to a good start (2006) or a bad start (2012) depending on the availability of milkweeds and nectar sources and the weather conditions that follow (2022). Lastly, a comprehensive demographic approach to the entire annual cycle will help us avoid interpretative leaps that are misleading or just flat-out wrong.

Much of this analysis is based on the use of the first sightings data assembled by Journey North. These data help define the timing of the stages and the variations from year-to-year help define how weather and the conditions from one stage to another determine population growth.

Migrating with Monarchs

by Denise Gibbs

Currently, I am a Monarch Conservation Specialist for Monarch Watch. Before that, I had a career as an interpretive naturalist, native plant nursery owner specializing in nectar and host species for butterflies, and teacher of a graduate course focused on butterfly conservation. But by far, my most satisfying endeavor (at the late Dr. Lincoln Brower’s urging) was researching Monarch migration and roosting behavior for the Chincoteague Monarch Monitoring Project at Chincoteague National Wildlife Refuge and Assateague Island National Seashore on Assateague Island, Virginia. For 23 fall seasons (mid-Sept to late Oct) I collected quantitative data from a 3X daily Pollard transect (driving census) on refuge roads, a daily point count on the primary dune, and 3X weekly count from the top of a hawk watch tower. In between, I netted and tagged Monarchs. I also conducted impromptu Monarch interpretation and tagging demonstrations for visitors on the beach and on the refuge’s tram tour. The data and my recommendations were included in a Monarch management plan for the refuge which was implemented and continues to benefit migratory Monarchs utilizing the refuge’s resources. But there was just one thing missing. I wanted to know where the Monarchs went after they left the island. I wanted to witness and experience the next phase of their journey…

From mid-Sept to late October 2022, my husband Rob and I journeyed along with Monarchs as they migrated along the Atlantic and Gulf coasts.

The day we left our home in the Verde Valley of central Arizona, our yard was nurturing all life stages of Monarchs. I wished them well and we headed north on I-17, which was lined in fields of gold — sunflowers, goldenrod, golden crownbeard, and goldeneye. AZ had an abundant and extended monsoon season this year — wildflowers and butterflies (including Monarchs) flourished. From Flagstaff, we drove on I-40 toward the East coast. As we traveled, high winds from the south were so strong we feared that Swan (our tall campervan) might be blown into other lanes on overpasses and bridges. Rob drove and I watched for migrating monarchs, but saw none; the wind was not favorable for Monarch flight southward. We drove through 9 states, but I didn’t see a migrating Monarch until a week later in downtown Norfolk, Virginia.

After that, we saw Monarchs every day at every place we stopped. We had several good Monarch migration days on the Delmarva peninsula and its barrier islands — at Assateague Island State Park in MD and Chincoteague National Wildlife Refuge (CNWR) in VA, before we got slammed with Hurricane Ian’s gale-force winds and coastal flooding. The rain was needed. Past years’ wet fields and ditches of Bur-marigold (Bidens laevis) were dry and barren this year. The rains came too late for them, but boosted the blooms of Seaside goldenrod (Solidago sempervirens), which were already late in opening their flowers. The first big wave of migrating Monarchs had to fly further inland from their migratory path along the beach to find the other two species of goldenrod that were in bloom: Slender and Grass-leaved. Groundsel-tree (Baccharis halimifolia) was beginning its bloom and was utilized by migrating Monarchs as well. As usual at CNWR, the wind was variable, and on most days the Monarchs flew (constantly flapping) in less-than-ideal winds. They stopped often to rest in places protected from the wind. Beach parking was limited after the hurricane removed all the public parking lots, so we had to park Swan along the narrow, exposed causeway. This proved to be fortunate for the Monarchs, because they used the vehicle as a wind block and as a place to rest (see photo).

When Bayberry/Groundsel-tree thickets were available, Monarchs would take refuge from the wind in the dense vegetation. But if they rode the wind to the over-washed beach area, they had to find other ways to avoid being blown out over the ocean. On a day with a 20-30 mph NW wind, a Monarch wedged itself in a crack in a wooden board along the saltmarsh boardwalk trail, while others clung to short plant stems on the beach (see photos below).

We left Virginia’s barrier islands and headed south, stopping to camp the first night at Kiptopeke State Park, which is at the southern tip of the Delmarva. With south winds, Monarchs were bottled-up, waiting for a north wind that would carry them safely and swiftly across the Chesapeake Bay to Virginia Beach. (We learned from a friend that their departure en mass actually occurred 5 days after we had left). In the photos below, Monarchs were hunkered down in the Bayberry thickets along the Eastern shore of the Chesapeake Bay when they were not nectaring on the abundant patches of Seaside goldenrod.

We headed south toward Florida, following coastal routes. We stopped at nature centers, welcome centers, and visitor centers. It was encouraging to see that every one of them had a pollinator garden. Some were simply wild patches they had allowed to grow; others were intentionally planted small token gardens, and a few had extensive professionally-designed beds. I did not see any Monarch Waystation signs, but I did see plenty of Monarchs in every garden. Nectar sources included native asters, goldenrods, and Blue mistflower. Only a few gardens contained milkweed— Butterfly weed and/or Tropical milkweed.

We also stopped frequently at every town that had available RV parking (with easy access to the ocean or a bay) to look for Monarchs. We saw them at EVERY place we stopped in VA, NC, SC, and GA. Back Bay NWR in VA was particularly good. Most often, the Monarchs we saw were refueling in patches of goldenrod instead of migrating. We hit the Monarch jackpot on a N wind day at Huntington Beach State Park in SC — a continuous stream of Monarchs flying low (10-20′ high) over the dry sand portion of the beach on a perfect N wind. There easily could have been 10,000 Monarchs by the end of the day (see photo).

Our final stop on the Atlantic coast was the beach at Tybee Island GA, but saw only a few Monarchs in a town-square pollinator garden with Lantana and Tropical milkweed. We turned inland, avoided the interstate, and took alternate routes to St Mark’s National Wildlife Refuge in FL. Roadside nectar sources were abundant but we saw only a few monarchs en route. We spent 2 days at the refuge. Winds were SW or S, so we saw no migrating monarchs — just those that were bottled-up at Lighthouse Point, nectaring on goldenrod, and waiting for the wind direction to shift in their favor. Gulf fritillaries by the hundreds kept the nectaring Monarchs company (see photos below).

The gulf coast from Florida to Texas was surprisingly good. We saw Monarchs everywhere we stopped to look for them. At Point Park Pascagoula, MS (near the birthplace of Jimmy Buffett), we hit another Monarch jackpot. In the 30 minutes that I walked down Buffett Beach, I counted over 1000 monarchs as they flew past me at eye level on a 10-20 mph N wind. Once they reached the point, they stopped to nectar in a dense thicket of Groundsel-tree. There were thousands still nectaring in those thickets when we left at dusk.

Our last stop on the gulf coast was at Sea Rim State Park, TX (NE of Galveston). We arrived at 3:30 PM and made a beeline for the beach. Low tide revealed a wide flat beach where Monarchs were migrating. I counted 52 from 4-4:30. (That was close to the number that Harlen had counted on his driving census along Lavaca Bay the same day). Then at 4:30, Monarchs started dropping down into a wide flat dune area full of goldenrod and other wildflowers. I counted a few hundred nectaring, but the area was so extensive (about 100 x 300 yards) that there were likely many more I couldn’t see. While searching, I found this pair mating (see photos).

Reluctantly, we left the Gulf coast and drove west on I-10 across Texas. We continued to see monarchs crossing the highway from north to south, particularly in the Texas Hill Country. In Kerrville, Monarchs were migrating along the Guadalupe River, stopping to nectar on Bidens and Blue mistflower (see photos below). The last migrating Monarch we saw in TX was in Ozona.

We crossed the state line into New Mexico on Oct 21. I continued to watch for those orange beauties as we drove west toward AZ. We saw no Monarchs in NM. There had already been below-freezing night temperatures and the roadside wildflowers were dead. Another cold front the next day caused the temperature to plummet, and snow was in the forecast for AZ’s White Mountains (our intended route home). Instead we stayed on I-10 to avoid the snow. We stopped in Wilcox to watch the arrival of thousands of Sandhill Cranes. Fleabane and Tansyaster were still blooming around the playa and were luring in Variegated fritillaries, Checkered whites, Queens, Checkered and Fiery skippers — but no Monarchs. Our final campsite of the trip was in the Sonoran Desert near Tucson. There were plenty of Monarchs present, so I felt like we had come full circle.

Final thoughts:
From 23 Fall seasons of watching migratory behaviors of Monarchs on Assateague Island, I already had a deep respect and appreciation for their ability to endure hardships and survive hurricanes, nor’easters, and flooded roosting sites. But all along this trip route, I was in awe of their continued resilience. Their ability to keep migrating despite obstacles was astonishing. They flapped directly into SW and S winds, endured long distances with a scarcity of nectar sources, and hunkered down on days with torrential rain, cold temperatures, gale-force winds, and coastal flooding. Along the Gulf coast they flew over developed beaches with no habitat, through the hazy polluted stench of paper mill exhaust, and over shipyards blasting ear-shattering horns and sirens. They took shelter in the most unlikely and inhospitable places. They got blown backwards or out over the ocean on extremely unfavorable winds, but kept flapping to stay true to their directional flight. The migratory urge (compulsion, drive, stimulus — however you want to describe it) keeps them going — against all odds. There’s a lesson in that for all of us.

2. Monarch Population Status —by Chip Taylor
——————————————————
The migration is underway!

EASTERN MONARCHS
The fall monarch migration has started and is slowly advancing southward through the northern latitudes. The leading edge of the migration sometimes arrives as early as the 23rd of August in the Twin Cites area (45N). Due to a delay in the development of the second generation in late May and June, it is likely this migration, consisting mostly of 3rd generation butterflies, will be late and drawn out. The numbers in the migration should be good from the Maritimes in the NE to as far south as northern Virginia. Lower numbers than usual are expected for the midwest. The drought in Oklahoma, Texas and Nuevo Leon (Mexico), could limit fall flowering and therefore the nectar needed by monarchs to fuel their migration. Such droughts are strongly associated with lower numbers recorded at the overwintering locations in Mexico.

WESTERN MONARCHS
It appears to be a great year for monarchs in the Pacific Northwest and by some accounts, it may be the best summer since 2017 or 2018. The summer heat hasn’t been too intense and a good fall migration is expected from this area. The numbers of monarchs in Arizona are about average this year which is good compared to a couple of years ago but lower than the numbers seen last year at this time. Utah and western New Mexico are having a really good year with many reports of abundant larvae/pupae. Northern and southern Nevada have both reported Monarchs but the Reno area in particular is reporting good numbers in comparison with just a few sightings in the south. Overwintering numbers in the west should be very good, as long as September temperatures in California are close to normal.

David James and Gail Morris provided information about the status of western monarchs.

3. Monarch Watch Tagging Kits
——————————————————
We are in the process of sending out tagging kits for our 31st tagging season – wow! As of today, all preorders and most recent orders going to locations north of (and including) Colorado, Kansas, Missouri, Kentucky, and Virginia have been mailed out. If you are located in that area and you have not yet received your tags, watch your mail for them to arrive within the next 10 days or so. Tags for locations further south will be mailed out soon – priority is always given to those tag orders going to locations that will experience the migration first.

Monarch tagging continues to be an important tool to help us understand the monarch migration and annual cycle – a long-term record is crucial to understand the dynamics of such complex natural phenomena. If you would like to tag monarchs this year, please order your tags soon! Tagging Kits should arrive within 10–12 days but as mentioned above, priority will be given to areas experiencing the migration first.

Monarch Watch Tagging Kits are only shipped to areas east of the Rocky Mountains. Each tagging kit includes a set of specially manufactured monarch butterfly tags (you specify quantity), a data sheet, tagging instructions, and additional monarch / migration information. Tagging Kits for the 2022 season start at only $15 and include your choice of 25, 50, 100, 200, or 500 tags.

Monarch Watch Tagging Kits and other materials (don’t forget a net!) are available via the Monarch Watch Shop online at https://shop.monarchwatch.org – where each purchase helps support Monarch Watch.

2022 datasheets and instructions are available online via the Monarch Tagging Program page at https://monarchwatch.org/tagging

Tagging should begin in early to mid-August north of 45N latitude (e.g. Minneapolis), late August at other locations north of 35N (e.g., Oklahoma City, Fort Smith, Memphis, Charlotte) and in September and early October in areas south of 35N latitude. See a map and tables with expected peak migration dates and suggested dates to begin tagging on the Monarch Tagging Program page at the link above.

4. Submitting Tag Data
——————————————————
We are starting to receive 2022 tag data but if you haven’t submitted your older data yet (for 2021 or even previous years) it is not too late. Please review the “Submitting Your Tagging Data” information on the tagging program page then send us your data via the Tagging Data Submission Form. In general, please try to submit your data soon after you are finished tagging for the season.

6. Monarch Waystations
——————————————————
To offset the loss of milkweeds and nectar sources we need to create, conserve, and protect monarch butterfly habitats. You can help by creating “Monarch Waystations” in home gardens, at schools, businesses, parks, zoos, nature centers, along roadsides, and on other unused plots of land. Creating a Monarch Waystation can be as simple as adding milkweeds and nectar sources to existing gardens or maintaining natural habitats with milkweeds. No effort is too small to have a positive impact.

Have you created a habitat for monarchs and other wildlife? If so, help support our conservation efforts by registering your habitat as an official Monarch Waystation today!

Monarch Waystation Program: https://monarchwatch.org/waystations

A quick online application will register your site and your habitat will be added to the online registry. You will receive a certificate bearing your name and your habitat’s ID that can be used to look up its record. You may also choose to purchase a metal sign to display in your habitat to encourage others to get involved in monarch conservation.

As of 20 August 2022, there have been 40,704 Monarch Waystation habitats registered with Monarch Watch! Texas holds the #1 spot with 3,374 habitats and Illinois (3,150), Michigan (3,014), California (2,657), Ohio (2,144), Florida (2,050), Virginia (1,789), Pennsylvania (1,780) Wisconsin (1,775), and Ontario (1,330) round out the top ten.

Greetings, Monarch Watchers.

It is with heavy hearts that we start this month’s communication by sharing this tragic news with the Monarch Watch community:

Three family members, formerly of Lawrence, killed in ‘senseless’ shooting in Iowa
https://lawrencekstimes.com/2022/07/23/schmidt-family-killed-iowa-shooting

Sarah worked for Monarch Watch in the early 2000s and she and Tyler both contributed greatly to Monarch Watch’s development and continuation. We are absolutely shocked by this horrific act of violence. Our thoughts are with all of Sarah’s family members as they try to move forward during this unimaginably difficult time. A GoFundMe campaign has been set up for her 9-year-old son who survived the attack.

——————————————————
1. Monarch Population Status
——————————————————
Each year at this time I summarize what I know about how the monarch population is developing. The idea is to give taggers a heads-up about what to expect during the migration. The trouble with this exercise is that the available data are often contradictory (like this year) and there never seem to be a sufficient number of observations. Also, there is often a lull in monarch activity in early July which can be misleading and critical weather information, particularly temperature summaries, needed to assess population growth can also be lagging. Ok, that sums up my excuses. Here is what I do know, based on first sightings reported to Journey North and temperatures from 8 Tempest weather stations scattered from eastern North Dakota to central Ohio.

The monarchs returning from the overwintering sites in Mexico arrived in Texas in noticeable numbers between 11-15 March which fits with the long-term pattern of arrivals. The numbers reported were somewhat lower than last year but average for the last 5 years. I was a bit concerned about the returning numbers at the time, but the overall timing and numbers reported suggested the population was off to a fairly good start.

I next focused on the timing and number of first-generation monarchs moving north out of Texas in May. The first two weeks of May can be a low period for first sightings, but there was a surge of these in the central part of the Midwest from about 10-20 May. That was something to cheer about since that push northward, aided by strong SW winds, was a sign that the population in the Upper Midwest would be off to an early start. But that was not to be. A week of cooler, less favorable, weather followed in many areas. In fact, there were large areas in the eastern Midwest where the cooler weather lasted for three weeks, substantially slowing population development. Added to these conditions, the total number of first sightings in the Upper Midwest was the lowest since 2019 and strikingly low for the area from Madison, WI to the central Dakotas (90-100W longitudes). It is this region that is best represented by tag recoveries in Mexico. Together, delayed development and lower-than-average numbers suggest that the migration in the Midwest will be lower than average in late August and September. It will also be later, which will enable taggers to in many areas to tag monarchs well into September in the north and October in the south.

While the peak colonization of the area from the mid Dakotas (100W) to western Pennsylvania (80W) occurred from 11-20 May, colonization to the east (80-60W) peaked from 21-30 May. The difference in timing between the Midwest and East was unlike any record in the past for May. In addition, the numbers reported in the east were the highest in the 22-year record. These reports amounted to 38% of all sightings. The numbers included 30 sightings in the Maritime provinces – almost double the previous high (17) for that region. The record of colonization in the east may or may not signal a larger than average migration in the east; it is simply too early to tell. But, like the Midwest, it seems likely that the migration will be late and offer an opportunity for tagging well into September and early October along the eastern monarch flyways.

2. Monarch Watch Tagging Kits for 2022
——————————————————
Monarch tagging continues to be an important tool to help us understand the monarch migration and annual cycle – a long-term record is crucial to understand the dynamics of such complex natural phenomena. Tags for the 2022 fall tagging season are available and we have started shipping preorders out this week, ahead of the migration in your area. If you would like to tag monarchs this year, please order your tags soon! Tagging Kits ordered now should arrive within 10–14 days but priority will be given to preorders and areas that will experience the migration first.

Monarch Watch Tagging Kits are only shipped to areas east of the Rocky Mountains. Each tagging kit includes a set of specially manufactured monarch butterfly tags (you specify quantity), a data sheet, tagging instructions, and additional monarch / migration information. Tagging Kits for the 2022 season start at only $15 and include your choice of 25, 50, 100, 200, or 500 tags.

Monarch Watch Tagging Kits and other materials (don’t forget a net!) are available via the Monarch Watch Shop online at shop.monarchwatch.org – where each purchase helps support Monarch Watch.

2022 datasheets and instructions are available online via the Monarch Tagging Program page at monarchwatch.org/tagging

Tagging should begin in early to mid-August north of 45N latitude (e.g. Minneapolis), late August at other locations north of 35N (e.g., Oklahoma City, Fort Smith, Memphis, Charlotte) and in September and early October in areas south of 35N latitude. See a map and tables with expected peak migration dates and suggested dates to begin tagging on the Monarch Tagging Program page at the link above.

——————————————————
3. Submitting Tag Data
——————————————————
Thousands of you have submitted your 2021 season tag data to us by mail or via our online submission form – thank you! We are still receiving data sheets and if you haven’t submitted your data yet (for 2021 or even previous years) it is not too late. Please review the “Submitting Your Tagging Data” information on the tagging program page then send us your data via the Tagging Data Submission Form.

Complete information is available at monarchwatch.org/tagging if you have questions about submitting your data to us and we have conveniently placed a large “Submit Your Tagging Data” button on our homepage at monarchwatch.org that will take you directly to the online form.

There you can upload your data sheets as an Excel or other spreadsheet file (PREFERRED; download a template file from monarchwatch.org/tagging) or a PDF/image file (scan or photo).

If you have any questions about getting your data to us, please feel free to drop Jim a line anytime via JLOVETT@KU.EDU

Coming Soon: we plan to have the Monarch Watch mobile app available in the App Store (Apple iOS) and Google Play (Android) in August which will allow you to record and submit your tag data, report recoveries of tagged monarchs, participate in the Monarch Calendar program, and more! We will announce the app via social media and you can keep checking our site for updates at monarchwatch.org/app

4. Tagging Wild and Reared Monarchs
——————————————————
As a reminder, the following is an abbreviated version of our “Tagging wild and reared monarchs: Best practices” article posted to our Blog in 2019. The complete text of the article is available via the link below.

Diving into the tagging data has revealed a number of surprises such as the difference between the probability that a reared monarch will reach Mexico and the probability that a wild–tagged monarch will do so. The recovery rate is higher for wild–caught monarchs (0.9% vs 0.5%) and it is the data from the wild–caught butterflies that tell us the most about the migration. Frankly, for some analyses, we have to set the reared monarch data aside. That doesn’t mean it is not valuable, but its uses are limited.

It should be noted that for tagging data purposes, monarchs captured as adult butterflies should be reported as WILD and adult monarchs reared from the egg, larva, or pupa stage should be considered REARED.

TAGGING WILD-CAUGHT MONARCHS
For wild-caught monarchs we need to:
1. increase the number of taggers from western Minnesota and Iowa westward into Nebraska and the Dakotas to give us a more complete understanding of dynamics of the migration;

2. increase the number of wild monarchs that are tagged since these provide the most valuable data; and

3. increase the number of taggers who tag from the beginning of the tagging season in early August until the migration ends. Tagging records for the entire season will help us establish the proportion of the late–season monarchs that reach the overwintering sites. When tagging wild–caught monarchs, many taggers run out of tags well before the season ends. That’s great, but it would help us to know when all tags had been used by indicating this via the online tagging data submission form.

TAGGING REARED MONARCHS
Reared butterflies tend to average smaller than wild migrants. That difference can be reduced significantly if careful attention is given to rearing larvae under the best possible conditions. Large monarchs have the best chance of reaching Mexico, surviving the winter and reproducing in Texas. There are several reasons for this: better glide ratio, better lift with cross or quartering winds, larger fat bodies, more resistance to stress, etc. There are very few small monarchs among those that return in the spring. For those of you who prefer to rear, tag and release, we have a few suggestions:

1. Rear larvae under the most natural conditions possible.

2. Provide an abundance of living or fresh-picked and sanitized foliage to larvae.

3. Provide clean rearing conditions.

4. Plan the rearing so that the newly-emerged monarchs can be tagged early in the migratory season (10 days before to 10 days after the expected date of arrival of the leading edge of the migration in your area).

5. Tag the butterflies once the wings have hardened and release them the day after emergence if possible.

6. When it comes to tagging, tag only the largest and most-fit monarchs (see complete article for some guidelines). Records of tags applied to monarchs that have little chance of reaching Mexico add to the mass of tagging data, but do not help us learn which monarchs reach Mexico – unless the measurements, weight and condition of every monarch tagged and released is recorded. There are a few taggers who keep such detailed records and those data can be very informative. If you collect such data and are willing to share it please contact us; do not add this information to the standard tagging data sheet.

As a final note, this text is not a directive. We are not telling you what to do; rather, we are simply providing suggestions that may lead to more successful rearing and tagging efforts. The expanded version of this article is available at

To offset the loss of milkweeds and nectar sources we need to create, conserve, and protect monarch butterfly habitats. You can help by creating “Monarch Waystations” in home gardens, at schools, businesses, parks, zoos, nature centers, along roadsides, and on other unused plots of land. Creating a Monarch Waystation can be as simple as adding milkweeds and nectar sources to existing gardens or maintaining natural habitats with milkweeds. No effort is too small to have a positive impact.

8. IUCN Red Listing of Monarchs
——————————————————
The recent news about the IUCN’s Red List does not change the status of monarchs in the U.S.

In a December 15, 2020 press release, the U.S. Fish and Wildlife Service announced its decision with respect to the petition to declare the monarch a “threatened” species under the Endangered Species Act:

“After a thorough assessment of the monarch butterfly’s status, the U.S. Fish and Wildlife Service (Service) has found that adding the monarch butterfly to the list of threatened and endangered species is warranted but precluded by work on higher-priority listing actions. With this decision, the monarch becomes a candidate for listing under the Endangered Species Act (ESA), and its status will be reviewed each year until it is no longer a candidate.”

Upon that announcement, we wrote that the “warranted but precluded” decision for monarchs is the right one at this time. It acknowledges the need for continued vigilance due to the numerous threats to the population while emphasizing the need to continue support for programs that create and sustain habitats for monarchs. It also should be clear that it is the North American monarch migration that is threatened and not the species, which is widely distributed in the Americas and elsewhere.

Please see our full response to this posted via our blog in 2020 at monarchwatch.org/blog/2020/12/15/esa-listing-decision-for-the-monarch/

Thank you for your interest and concern!
