Blue-winged Olives
Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

I spent more than an hour casting to several rising trout in this pool and caught only two. Its clear water and tricky currents harbor dozens of free-rising, usually very hard-to-catch fish.

This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.

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.
