What is the minimum time after emerging that I can tag my butterflies? I have had several come out around noon. They are itching to get going, but I believe I have to give them some more time before tagging.
I know it might be a bit early to tag (I am at 44N) but I have ordered more tags so I won't be short. Since they are congregating at Point Pelee already, I don't want to miss tagging anyone who might be on the start of their journey.
