Aquatic larva - Chauliodes

Fishfly larva

I went back to the stream where I photographed this guy and took home a specimen, with the intent of rearing it. I gave up that when I discovered they could take up to 5 years to mature, so he is now resting in a vial. Anyways, a little research identified this as a fishfly larva, since it doesn't have adbominal gill tufts like a hellgramite (dobsonfly larva). An excellent document, http://creekconnections.allegheny.edu/Modules/On-LineActivities/AquaticMacros/aquaticinsectfactsheets/fishfly.pdf, is packed with information on fishflies.

fish fly?

There's only images of adults currently in the Guide but there's a pic of a Sialis larva on this page showing abdominal gills and a pointed terminal appendage. Possible?

Dobsonfly Larva

This looks like the Larva of a Dobson fly. The larva are known as Hellgramites.

Corydalidae.

Pretty small to be a hellgrammite, though it could be a young one. It is definitely the larva of something in the family Corydalidae.

What's That Bug

I was looking at What's That Bug's Hellgramite page. They look very similar to me.
