Big, Black, Shiny Bug
Tue, May 26, 2009 at 10:11 AM
We saw a number of these bugs by a river on the CT/MA border after a rainstorm in late May. They didn’t hesitate at puddles, but swam straight across and walked out on the other side. They were about 3 1/2 inches long, black, shiny, and had spines. They didn’t seem to be aggressive. What are they?

Hellgrammite

Hi Sandi,
This is a Hellgrammite, the larval form of the fierce looking but harmless Dobsonfly. Hellgrammites are considered to be one of the choicest baits by many fishermen. We just recently posted another photo of a Hellgrammite in its subterranean burrow.

Ha!  We thought they had a Dobsonfly like shape!  Thank you!  Our curiosity is satisfied…until next time!
blessings!!!  Sandi
