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.

Kogotus Stonefly Nymph Kogotus Stonefly Nymph

This one pretty clearly keys to Kogotus, but it also looks fairly different from specimens I caught in the same creek about a month later in the year. With only one species of the genus known in Washington, I'm not sure about the answer to this ID.

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.

Quick evening trip to the South Fork Snoqualmie

By Troutnut on July 19th, 2019

My wife and I drove up to the nearest trout stream for some quick evening fishing. I hoped to put her on some fish in the pools that allowed easier casting, but they seemed oddly devoid of fish. The ones I caught were rising sporadically, tight against cover that would snag most flies and required precise presentation. Retention is allowed on this stream, so I think maybe the easy pools got fished out.

Little green stoneflies (likely Alloperla) were common in the air in this fast-water reach, and I saw several on the water too.

A few of these larger stoneflies were fluttering around the South Fork on an evening dominated by much smaller species.

This one has been difficult to identify. I can't spot any of the gill remnants characteristic of Perlidae, but the wing venation seems to point in that direction. I tried keying it out as Perlodidae but arrived at Isoperla, every western species of which has significantly smaller bodies than this one.

Edit: See forum comments for a likely correct identification.
