Female Dobsonfly

5735 This photo was taken in Auburn, Ontario. My name is Jason O’Reilly. It landed on my kitchen window and stayed there all night and never moved an inch.

This is a female eastern dobsonfly, Corydalus cornutus (Megaloptera: Corydalidae); their aquatic larvae are known as hellgrammites and often used as fish bait.
