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

Dorsal view of a Kogotus (Perlodidae) Stonefly Nymph from Mystery Creek #199 in Washington

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.

I seined several nymphs in the drift tonight, but all of them hatched within minutes. If I got one into my vial, by the time I put another one in there, the previous one was ready to get back out. Maybe next time I'll take a vial of rubbing alcohol to dissuade them from hatching.

I got these three guys from kicking over some rocks. I can't verify that they are the same ones that were hatching today - I just picked ones that were most similar to those I saw actually hatch. I think a few of them actually did begin to hatch in the vial but didn't make it, so they might just be the same species as the ones producing the duns on the stream.

Also, notice how much better the pic is. I thought the photos I'd been sharing with you guys were taken with my wife's good macro lens, but I was mistaken (shows you how much I know about cameras). From now on, I think it should be easier to see detail in the images I post.
