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.

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.

Female Caenis (Angler's Curse) Mayfly Dun Pictures

Here's a goofy picture of a Caenis dun falling off the back of a leaf, never to be seen again.  These mayflies are very tiny and fragile, and very hard to capture and photograph without damaging. This little dun hatched from the nymph in a tub of nymphs while I was picking through for aquatic specimens to photograph... I grabbed the leaf it hatched onto and tried to take some pictures but it got away after about half a picture.
