Pteronarcys californica

The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

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.

Small Eastern Blue-Winged Olives

Like most common names,"Small Eastern Blue-Winged Olive" can refer to more than one taxon. They're previewed below, along with 1 specimen. For more detail click through to the scientific names.

Mayfly Species Baetis intercalaris

These are pretty much always called Small Eastern Blue-Winged Olives.

Mayfly Species Attenella attenuata

These are often called Small Eastern Blue-Winged Olives.
This intriguing species has received a lot of attention in past angling books. Recent authors suspect that much of this credit was a case of mistaken identity, with Attenella attenuata receiving praise for the hatches of Drunella lata and Dannella simplex. Much of the credit was legitimate and accurate, but this species is no longer thought to be on par with its most popular cousins in Ephemerella and Drunella.

I have several specimens listed under this species, but I'm not positive the identification is correct.
