Thnx guys....it's much apreciated

Tom, As you can see my realistic work has no hook eye...it's there but in this case, it's nose is the front of the hookeye covered with a strip of nymph skin. You could fish it if you leave the hook eye exposed. I would use a different wing material too but otherwise it wouldn't be any problem. Tying a dozen or so would keep you bussy for about a week so it might be better to use an easier tyable pattern

I think you might have found a Dobsonfly? The adult that crawls out of the hellgrammite? The mandibles make that a reasonable asumption I guess.
The Nymph doesn't have these large mandibles but the adult male's do so if it just emerged (which they do in the mub in the riverbanks)? It's a common insect in your area if I'm informed correctly.
The color is not very stone fly either...these would be brownish. The Dun plumb color says Dobsonfly too. The wings of a Dobson fly are larger compared to the body of the insect than the one's of the stone fly. Stone fly wings are as long as the body and dobson fly wings are much longer than the body so that's quite a difference. Some species can grow up to 4 inches but around New Jersey 2 inches is common. I probably don't have to tell you but the nymph's bite....hard

Just google dobsonfly and see if that's the right insect...and please let me know...I'm kind of currious

My knowledge of these bugs is based on internet so I might be wrong here.
Here is a link to get you started.
