Fabulous lecture, professor Melanie! Love the story about the prof eating the caterpillars.
I'll for sure start taking more pictures of butterflies now, although I mostly have monarchs, Zebra Longwing and Frittilaries.
What do you call it when you come upon a whole group of Zebra Longwings 'roosting' on a branch - this was late one evening and it was too dark to get a picture but there were at least 6 of them all hanging on one twig and I sort of blundered into them, disturbing a couple before I realized they were there. Are they sleeping, or mating or what?
