I found this caterpillar crawling along the edge of my burning barrel. I have a caterpillar book, but I can’t find it in the book. Can you tell me what it is? I live in western Penna.
This looks like a Pale Tussock Moth, Halysidota tessellaris, also called the Banded Tussock Moth. It feeds on oaks, willows, poplars, hickories, and many other forest and shade trees
