Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.
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.

The June-July 2013 Fly Fisherman mag has an interesting article in it from James Prosek called, "The Diversity of Trout"...It addresses our discussions here, from time-to-time, about the issue of species etc. IMHO...It is worth the price of admission.
"Darwin expressed his frustration with the word species and questioned where to draw lines amid infinite beauty and diversity."
There are a couple other articles to spice it up...They are PA oriented :), seems to be in vogue this year :)...One on Hexagenia autrocaudata by some guy named Paul Weamer ;), and one on "Allegheny Browns". Mr Weamer is our neighbor on Penn's Creek where Eric and I bought our angler's hut this past spring...:)
Also rather timely for Spence, an article on Nectopsyche showing up in force on the Firehole and Madison.
