Large, any sex (male or female), reared or wild.
I recommend allowing wings to dry at least 24 hours on reared. Have every thing ready before you pick up the butterfly. Use a toothpick and have the tag ready before you pick up the butterfly. Use the toothpick to remove the tag. Don't touch it without your hands. The oils from your hands can prevent the tag from adhering properly. I just catch a small edge of the tag with the toothpick. Place it in the right place over the discal cell--website below has a picture. Press gently. If you press too hard, the tag will catch your skin and pull off (oops).http://www.monarchwatch.org/tagmig/tag.htm

She shows you how to hold the butterfly, but please don't handle the tag, use a toothpick.
