Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

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.

Perfect Candidate for a Woven Fly

But which weave?
Both the "Crisscross" and the "Mossback" (according to pics in Leeson & Schollmeyer) look to me anyway as being good candidates, but before I climb that mountain, was wondering if anyone here has a strong recommendation.

This reminds me of the time I met this guy who was good at weaving flies, so I tried to butter him up to give me a few. I did that by bringing him to a private spot where I had access. I put him on fish. He caught fish. He never said thanks, and I never got a fly. Oh well, hope springs eternal.

From the anal gills and the markings, this appears to be Agnetina--probably capitata.
