Dear Steve,
Despite his fearsome appearance, this male Dobsonfly is perfectly harmless.

Female Dobsonfly: Ventral view

Dear Cyndi,
This is a female Dobsonfly.  Though considered harmless, she has powerful mandibles that should be avoided as she can deliver a painful bite.

Hellgrammite

Dear Enrique,
This is a Hellgrammite, the larval form of the Dobsonfly.  Both adults and larvae are quite fierce looking, but they have no venom and they are harmless to humans, though female Dobsonflies and Hellgrammites have powerful mandibles that might deliver a painful pinch.  Freshwater fishermen often use Hellgrammites for bait.

Thanks man! That’s crazy, when I saw it I had no idea what it was lol

Your letter to the bugman:  Saw this walking on the snow.  Some kind of wood eater?  There is natural hot springs in the area.

Fishfly Larva

Dear Dylan,
Because the critter in your image looks so similar to a Hellgrammite, we are concluding that it is a nymph in the same family, and that it is most likely the nymph of a Fishfly.  Unfortunately, there is not much visual documentation of the larvae of western species.  What excites us most about your submission is that we can tag your posting as a Snow Bug.

Your letter to the bugman:  This weird bug was hanging around my dock in June. It had a very long body, and was pretty clumsy when it flew. It looked as though its body was to heavy to support it. It hung out in the cedars for a long time and then disappeared. I have tried to figure out what it is through google, a bug book and friends and no one has a clue! Hoping you can help!

Dark Fishfly

Dear Martha,
This is not a butterfly.  It is a Dark Fishfly in the genus
Nigronia which is pictured on BugGuide where it states:  “Emergence of adults may be synchronized. Adults are diurnal (seen flying near streams) and also nocturnal, so come to lights. Eggs are laid on the underside of vegetation overhanging a stream. Larvae are aquatic, predatory. Perhaps take three years to mature in more temperate areas, such as West Virginia. Pupation occurs in earthen cells on the edge of streams.”

Male Spring Fishfly

Dear Selcuk,
You are correct.  We believe this is a male Spring Fishfly, which is pictured on BugGuide.
