Hellgrammites/Dobsonflies (Please Read)
January 10, 2010
Hellgrammites can live completely submerged in water. They have gills all along there segmented bodies. They live for a few years in their larval stage. Then they come to land to pupate. They stay in their cocoon throughout winter only coming out to mate. They only live for 7 days as Dobsonflies. They mate, lay eggs and then die. During these 7 days the are thought to not eat at all. In there larval stage they are attracted to light because they are nocturnal. Just thought that I would give you a little info. I have been using these as fishing bait for around 15 years now.

Thanks for your comment. Recently a writer named Thomas requested permission to reproduce one of our Hellgrammite images for an article he is writing for an Angler’s magazine, and he has promised us that we may reproduce that text once the magazine is published this spring. We are including a couple of Hellgrammite images from the past with your letter since you did not provide one.
