Name that Bug
Hi! I found your site while web searching for the identity of this little critter. He’s easily 5 inches long and we found him in the back yard in eastern PA near NewHope getting ready for a family picnic. I’ll send you a second picture of the full bug.

We have been waiting for the photos of the Hickory Horned Devils, caterpillars of the Royal Walnut Moth, Citheronia regalis, to arrive. This is America’s largest caterpillar, and although fierce looking, it is harmless. It feeds on the leaves of trees like Walnut, Hickory and Persimmon. In the fall, the caterpillar leaves the tops of the trees and climbs to the ground where it will dig and pupate, emerging as an adult moth in the spring. We hope you are releasing your captive.
