Eastern Dobsonfly (Female) - Corydalus cornutus This dobsonfly was absolutely huge! It was about 11-12 cm long. There was a smaller female nearby, but still impressive at around 10 cm.

        Please tell everyone how you ran away and sat crying in the corner, shivering in fear. I need it for self confidence. Posted 6 years ago

The Eastern Dobsonfly

The eastern dobsonfly, "Corydalus cornutus", is a large insect in the Corydalidae family. It is found in eastern North America in regions with fast-flowing streams where its aquatic larvae develop. These are known as hellgrammites and are among the top invertebrate predators in the streams in which they live. They are used by anglers as bait.
