Salmonflies
Pteronarcys californica

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

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.

Looks pretty good. I'm not sure I would use rusty brown dubbing, though -- maybe mix about 2/3 rusty brown, 1/3 medium gray/dun. It'll look a bit too light and get darker in the water.

Take a look at Fly-Fishing Pressured Water, by Lloyd Gonzales, aka Gonzo. I've been tying his patterns, trying all the mayfly styles that seem appropriate for baetis.

Here is another, Rs2 style emerger I like, but I sometimes use a biot for the body. I like the tail sparse to imitate the shuck. This works as a wet fly also.

Hook- Tiemco 921 16-20. Measure this short hook to get the right size for the fly.
Tail-dun CDC or aftershaft feathers. Tie in a
Clump 3/4 as long as the hook shank and secure it at the
Bend of the hook. Wind the thread forward to form a thin tapered body.
Tie in a clump of stripped CDC or aftershaft feather to form the
Wing Sprouts. Or use CDC tips. The wing should be 1/2 the length of the hook shank. You can tie in longer and trim. Whip finish.

adapted from: Little Lehigh Flyshop

scroll down a bit to find the original pattern
