Isonychia (family Isonychiidae)
Jo-

That would be an Isonychia female imago, but 1" sounds excessive for the body length excluding tails. There are two Isonychia species in Pennsylvania, I. bicolor with a maximum imago body length of 17 mm., and I. hoffmani, whose maximum imago body length I don't know, but I doubt it is more than 21 mm., and more likely, less.
