Confidence: I'm as sure as I can be.
Notes: Many different species of caddis live in the small upland lake where these larvae came from. They were taken from the stomach contents of a brown trout caught today. The 2 larger ones appear to be the same species and any help with an ID would be appreciated. There were no case remnants which is strange if they are cased caddis but maybe they are not. The hard heads were all that remained so no body to study.
