Grey knobby, hairless caterpillar found in GA mountains
April 25, 2010
Hello. My children found this caterpillar one evening after dark in the north GA mountains. It is about 1.5 to 2 inches long, and as big around as a pencil at its widest point. Any idea what this guy is, and or what he will become?
Thank you so much

Underwing Caterpillar

We are confident that this the the caterpillar of an Underwing Moth in the genus Catocala, and you may compare your photo to an image from North Carolina posted on BugGuide.  Underwing Moths get their names because they are masters of camouflage with upper wings that allow the moth to blend into the bark of a tree when it alights.  The underwings are often brightly marked with red and orange stripes, and when the moth is flying, it is rather flashy, but upon alighting, the bright colors are hidden and the predator easily overlooks the resting moth.

Thank you so much!  My kids will be thrilled to know what it is!
