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.

Dorsal view of a Zapada cinctipes (Nemouridae) (Tiny Winter Black) Stonefly Nymph from the Yakima River in Washington
Nymphs of this species were fairly common in late-winter kick net samples from the upper Yakima River. Although I could not find a key to species of Zapada nymphs, a revision of the Nemouridae family by Baumann (1975) includes the following helpful sentence: "2 cervical gills on each side of midline, 1 arising inside and 1 outside of lateral cervical sclerites, usually single and elongate, sometimes constricted but with 3 or 4 branches arising beyond gill base in Zapada cinctipes." This specimen clearly has the branches and is within the range of that species.

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.

This old grayling had some serious battle scars on its dorsal fin, something I've never seen before catching many hundreds of fish.

This nice grayling (about 17 inches) was the lone resident of a deep, practically still-water pool in a low-flow side channel of the upper river. I coaxed it out with a risky sidearm cast into a narrow window under some low-hanging brush, a feat about which I must brag to make myself feel better about my next several attempts at impressive casts, all of which resulted in wading across the river and spoiling the pool to retrieve the fly from a tree.

This pretty little grayling fell for a well-placed beetle imitation.
