      The females can pierce skin with those mandibles though! Painful but still harmless, of course! Posted 4 years ago

    Very nice! I get so many of these at my light and love them! They creep me out when they fly around though. Posted 4 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.
