I was busy uploading far too many pictures for an upcoming (and much-overdue) post, and I thought, "Hm, it seems like I'm missing something I usually do so far... Oh yeah!"
It probably says something about me that I don't find these caterpillars "weird." Changing their diets to other insects? What's weird about that? What's weird are the ones that seem to think they're actually spiders and use their silk in large volumes to help them capture their prey in various ways (my favorite is one I read about years ago that used its silk as a shelter against its aggressive, fast-moving and numerous prey, only popping out to pick off one and then retreat), although even they aren't that weird.
