Blue-winged Olives
Baetis
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.

fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or

In the past month I've added a large number of new specimens to the insect encyclopedia, photographed on trips to the Montana/Wyoming/Idaho area for the last two summers. I haven't learned my Western hatches very well yet, so I'm relying on expert help (or slowly trudging my way through keys as time allows) to identify most of them.
To make this process easier and also catch up on specimens that have fallen through the cracks over the years, I created a page that automatically lists specimens that aren't identified as specifically as one could reasonably expect. I'll use this to guide my own ID attempts and I hope it helps some of the other experts who like to weigh in here.
The new page is called identification needs, and it's linked from the top of the Aquatic Insect Encyclopedia page for easy access once this post falls off the front page.
