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

Onocosmoecus (Great Late-Summer Sedge) Caddisfly Larva Onocosmoecus (Great Late-Summer Sedge) Caddisfly Larva

Lateral view of a Onocosmoecus (Limnephilidae) (Great Late-Summer Sedge) Caddisfly Larva from the Yakima River in Washington

This specimen keys pretty easily to Onocosmoecus, and it closely resembles a specimen from Alaska which caddis expert Dave Ruiter recognized as this genus. As with that specimen, the only species in the genus documented in this area is Onocosmoecus unicolor, but Dave suggested for that specimen that there might be multiple not-yet-distinguished species under the unicolor umbrella and it would be best to stick with the genus-level ID. I'm doing the same for this one.

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.

Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

Serotonin posted these pics without a message, so I'm posting a quote from another thread in which I believe he references these pics --Troutnut

First, I'd like to say that I've really enjoyed this site since its inception, and I like it even more w/the new format. There is an incredible wealth of knowledge here.

I have encountered the bug pictured above, in a New York stream. I don't recall it's Latin name, but if memory serves, in Schwiebert's "Nymphs" he refers to it as a Snipe Fly Larva. I have also heard it called a Water Sprite.

I don't have the Nymphs book in front of me, but here's some photos I took a few winters ago. When disturbed, the things would thrash wildly until able to gain a foothold on something. I am considering making highly articulated larvae to mimic this behavior. Appx 1.5 cm.
