My friend found this caterpillar in south-central Tennessee in August. No identification guides or databases I've searched had a similar picture. Does anyone know the name of this species?

It is hard to be sure without clearer pictures, but that looks like something in the genus Eriocampa and it could be a Butternut Woollyworm (Eriocampa juglandis).

These are the larvae of a sawfly (so not technically a caterpillar) and are about 1 inch long.
