Blue-winged Olives

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 Skwala nymph still has a couple months left to go before hatching, but it's still a good representative of its species, which was extremely abundant in my sample for a stonefly of this size. It's obvious why the Yakima is known for its Skwala hatch.
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.

Guys, Sorry. For some reason I'm having a heck of a time posting the photo of the bug for you to ID. Didn't mean to post the first one without a photo and certainly didn't want to post the blank above. Rats.
Anyway, if you want to view the insect get on TroutUnderground.com and search for the post about Bitterroot Skwallas and what I've been calling Ameletus mays. It appeared last Spring. Got a nice picture of a dun on a cork handle that should provide enough diagnostic clues.
