Very cool!
You found a most interesting insect called a 'humpwinged grig.' They are most closely related to katydids and crickets, but are in a family all to themselves (Prophalangopsidae). The genus is Cyphoderris. Looks like this is a nymph, not sure which gender. They get a little larger than this. Nice find:-)

hump-winged grig
Thanks for the quick ID. I just stumbled across this website -- what a fantastic idea! I'm new to insects and this provides a great educational service. Now I'm off to learn more about hump-winged grigs (never even heard of them before...). Bob.
