hello, I am stumped and the fish biologists here are shrugging and throwing out guesses as to what I have here.

most think its a diptera with the legs already dissolved but I disagree, its a hard casement and all of the ice out brook trout are full of them in the ponds here in S. VT.

what the heck are they?

half an inch in length to almost an inch, I will try to dissect one open this week if I catch more with them in it.

any help, would be thankfully accepted!

That is an aquatic soldier fly larva, family Stratiomyidae, probably genus Stratiomys. Please see this photo by Tom Murray.

Fantastic! Thanks for the fast and accurate reply, these were new to me and I knew they weren't something with partially digested legs missing.

I'm very glad I found this site, great folks and very knowledgeable and helpful!
