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

Dorsal view of a Kogotus (Perlodidae) Stonefly Nymph from Mystery Creek #199 in Washington

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.

My God! Does that Touchet River have every known aquatic insect known to fly anglers?

Hi Sayfu,

Most small freestones have surprising biodiversity as compared to larger rivers, tail waters, and especially spring creeks. Very few species (if any) necessarily constitute what we would refer to as fishable hatches, let alone be the cause for selectivity.

Regards,

Kurt
