Well, although I only bought 400 and received another 35 "loaner" tags this year, I have just released my 500th reared Monarch of the season, yesterday. I still have 41 tags with about 150 chrysalis and 50 cats. It has been a busy but rewarding year. This morning, there were already 18 open and hanging with the nice upper 60's overnight temp's.
Next year, I will plan better. I never expected to get situations such as the female that dumped 110 eggs a couple of weeks ago in a two-day period.
Here on the East Coast, we usually see a large passing of Monarchs in the first two weeks of October. Hopefully, they can ride those northeast winds and get some distance between them and the coming frosts.
