Tonight we noticed a bunch of these on a dirt pile in our yard. We counted 11 of them. Can you please tell us what they are? None of us has ever seen a caterpillar with a spiky bum before 🙂
Signature: Thank you, Jen
This is a very dark form of the highly variable Whitelined Sphinx Caterpillar, Hyles lineata. It is the only member of the genus that the Sphingidae of the Americas website reports from Virginia.
