The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

Glossosoma (Little Brown Short-horned Sedge) Caddisfly Larva Glossosoma (Little Brown Short-horned Sedge) Caddisfly Larva

Dorsal view of a Glossosoma (Glossosomatidae) (Little Brown Short-horned Sedge) Caddisfly Larva from the Yakima River in Washington

I caught this tiny larva without a case, but it seems to key pretty clearly to to Glossosomatidae. From there, the lack of sclerites on the mesonotum points to either Glossosoma or Anagapetus. Although it's difficult to see in a 2D image from the microscope, it's pretty clear in the live 3D view that the pronotum is only excised about 1/3 of its length to accommodate the forecoxa, not 2/3, which points to Glossosoma at Couplet 5 of the Key to Genera of Glossosomatidae Larvae.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

last year about this time i went to my local river and saw the trout feeding on the surface on small green worms. 1-2mm in diameter and 10-15mm long. i couldnt tell where they were coming from. honestly it looked like i could tie a short piece of bright green ribbing on a hook and catch fish. sorry i don't have a picture but i'm going out this week and i'm hoping to get one. has anyone encountered this?

I have seen nothing more beautiful than the sunrise on a cold stream.

sounds like caterpillars that dropped off of trees. some species go into a wandering phase before they pupate (go into the cocoon phase of their life cycle). I've been seeing black ones lately.
