Hickory Tussock Moth
Lophocampa caryae

Lophocampa caryae, the hickory tiger moth, hickory tussock moth, or hickory halisidota, is a moth in the family Erebidae and the tribe Arctiini, the tiger moths. The species is widely distributed in the eastern half of North America. In other species in this family, the caterpillars acquire chemical defenses from their host plants, so they are potentially toxic or unpalatable, but despite anecdotal claims that this species may also be venomous, no venom has yet been isolated or identified; adverse reactions are characterized as irritant contact dermatitis.
