This topic is about the Hellgrammite Genus Corydalus
The largest and most well-known hellgrammites belong to this genus, although in my collecting experiences the fishflies of Nigronia seem to be more common in trout streams.

| Posts: 1 | Far from a fly-fisherman, I still wanted to identify a menacing- looking insect which invaded our late-night campfire council this past Memorial Day Weekend in Millford, PA on the Delaware River (cr 206 n). We stayed at Kittatiny Canoe Campgrounds, very commercial, but made the best of it. The amount of these bugs crawling around at night, lured by our glowing fire, was incredible. Today I identified them as Hellgramites, and also learned that they are prized by bass and trout. Didn't even think to bring a pole with the short weekend - we went rafting instead. Still wanted to inform fellow fisherman of the abundance and location of this critter. Important to note that our sites bordered the river - one website I read indicated that Hellgramites won't go more than 50 yards inland from their water source; I'm not sure if that's common to most aquatic species but I'd imagine so. | |

 Posts: 2733 | I think the adult, winged insect, is called a Dobson Fly. They seem attracted to light and fly around in the night and can scare the heck out of you as they have big wings and pincers. | |

Site Editor "Bear Swamp," PAPosts: 1681 | ...one website I read said that Hellgrammites won't go more than 50 yards inland from their water source.... Yemoss, that may have been referring to the travels of the Dobsonfly larvae (hellgrammites); they pupate terrestrially. Many adult aquatic insects are attracted to lights, often quite some distance from stream or lake. | |
