Despite the interesting pattern on this little moth's wings I didn't recognise the species and had to do some digging in my Peterson Field Guide to Eastern Moths. Sad to say this excellent resource has been out of print since 1996, but there's a new incarnation ... Moths of Northeastern North America.
The larval food plant is none other than the dreaded Toxicodendron radicans, a.k.a. Poison Ivy. Despite this plant's bad reputation it is a food source for many wildlife species.
