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

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.

I found this helpful web site by accident this afternoon while researching the body color of the Grannom found on the Little Juniata. The site lists the Latin name and I think the colloquial name. Then it goes on to provide the body and wing colors and the names of common fly patterns that represent that insect and it even provides data on how to fish the fly.

Then if you scroll down you can select another insect to find data on it.

Westfly, along with this site, has been one of my go-to resources for bugs and patterns to match them with, for a very long time.It is the most comprehensive site for for Western Fly Fishing that I have found. Another site I frequent is Steve Schalla's "Fly Fishing The Sierra", which has just about everything one would want to know about visiting and fishing that part of CA:
