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.

As far as I can tell, this species has only previously been reported from one site in Oregon along the Columbia gorge. However, the key characteristics are fairly unmistakable in all except for one minor detail:
— 4 small yellow spots on frons visible in photos
— Narrow occipital spinule row curves forward (but doesn’t quite meet on stem of ecdysial suture, as it's supposed to in this species)
— Short spinules on anterior margin of front legs
— Short rposterior row of blunt spinules on abdominal tergae, rather than elongated spinules dorsally
I caught several of these mature nymphs in the fishless, tiny headwaters of a creek high in the Wenatchee Mountains.
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.

Here are a few pics of my cicada ties I discuss in http://www.troutnut.com/topic/688. I am embarrassed to share pictures of such (poor) quality on this venerable site, but this is the best I can do without my wife's help. Ugly pics of ugly flies, I guess - these flies aren't meant to be pretty. The body of each runs about 1-1/2" long.

Those look good! Very generally "buggy," plus you nailed the bulky size and shape of the cicada and the segmented look of the abdomen.

Thanks, guys. I see Jason's cicada pics on this site show a bug that's more black and yellow, not so orangish. My guess is that different broods are slightly different colors. Since the hatch comes and goes so quickly (and doesn't repeat itself again for awhile!) it makes sense to try to be prepared ahead of time. But I'm not sure how you'd get a picture or a natural from your locale ahead of time, unless some old-timer has one from the last time they were around.

Best of luck, RleeP. Hope you get to fish the hatch of a lifetime - I wish I had.


P.S. By the way, Jason, the second fly is one I was fooling around with that time we went bass fishing and you were doing well on the DD. I had caught a few bass on it before, and what else am I going to do with them now? Not so great that day, though...

They look excellent to me as well. I believe the 17 year locust is generally more red or orange, while the annual locusts around here have green backs and grey bellies. Fly Fisherman had an article on cicadas with pattern (when the 17 year locusts were hatching a few years back) that I believe was called the mondo backing cicada.
