giant fly - Corydalus cornutus

giant fly - Corydalus cornutus
northfield, New Hampshire, USA
July 25, 2007
Size: over 3 inches/8 cm
i got it in my apartment at night, after a day with my balcony door open.

Looks like...
Corydalus cornutus (Linnaeus, 1758).

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.

not an expert ID but
Looks like a dobsonfly to me.

 
thanks guys, you are right!!!
