Dobsonfly
Check in the guide under either Dobsonfly or Corydalus...your "giant fly" is a female...take a look at at the males and their large mandibles, almost scary. The larva which live in steams and lakes are called helgamites and commomly used for fish bait. Great find.

We call them helgamites.
They are scary looking but the trout love them. Best natural bait you can get.
