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.

Kogotus Stonefly Nymph Kogotus Stonefly Nymph

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.

Jason:

I am simply amazed at how nice the new site is. I have been a fan of your work since I found the old site several years ago. As a biology teacher, I have used your site to help students involved in a stream sampling project notice the subtle differences between different aquatic organisms and to understand what they find. As a flyfisherman, I constantly find myself referring to your website for help at the tying bench.

Congratulations on having the best aquatic insect site on the web!

Thanks,

Rick McClelland

Hi Jason,
You probably know me from other forums. Since you are not far from where I reside, I decided to join. The site looks great! with lots of good info. I'll be suggesting it to all my friends and family that enjoy fly fishing.

My best,
Mark
