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.

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 caught the morning Trico hatch on Silver Creek and landed quite a few difficult mid-sized rainbows, while watching my fly spurned by ten times more.

The Wind River starts out small at this location near the Tie Hack Memorial. The pools look good, but I caught no fish in several pools and only saw one riser that hit my fly with half a dozen splashy refusals.

Closeup insects by Troutnut from Mystery Creek #304 in Idaho

A few good small creek bugs

By Troutnut on June 12th, 2022
I was traveling on the east side of the Cascades today, where all the rivers are ridiculously high from a combination of snowmelt and rain. It's dangerous to even get in the water. But I found a place to sample a few bugs in a small creek and added a couple stoneflies from my to-do list.

I'm not aware of any way to tell the two species of Doroneuria apart as nymphs, so this one is classified to species based on location alone. Doroneuria baumanni is found in the Cascades and in Washington, and the other species is not known here yet.

Ruler view of a Cinygmula (Heptageniidae) (Dark Red Quill) Mayfly Nymph from Swauk Creek in Washington The smallest ruler marks are 1 mm.
This one doesn't have the protruding mouthparts typical of Cinygmula, but I think it's just an oddball individual.
