Even though they are feeding on black walnut leaves, the common name for your Sawfly Larvae is Butternut Woolly Worm, Eriocampa juglandis. Sawflies are non-stinging relatives of bees and wasps. According to BugGuide: “larvae peculiar, covered with long threads of wax.”
Thanks! Peculiar little buggers!
