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.

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.

tying for the next few weeks' hatches, and concentrating (for once!) on spinners since I've tended to tie LOTS of nymphs and duns that will rarely be fished...gotta diversify, try something I've ignored too much.

March Browns, Iso's, the drakes and other stuff for 'up north' is going into the vise.

Right now, and for the past five weeks, I've not tied a single fly. I had cataract surgery on my right eye April 17, and on my left eye on May 08. Now my intermediate and distance vision is 20/20 without glasses my close-up vision is totally gone. Prior to the surgery I was able to tie to #22 with out my eyeglasses and now I can't tie anything. I go back in two weeks for a vision exam and to determine what prescription eyeglasses I need for reading, computer, and most important, tying flies. I have a couple of pairs of readers now for the computer 2.50 & 2.75 diopters. I bought a pair of 2.5X magnification Flip Focals to tie knots and change flies on the stream and change flies. They work very well but I must wear the readers in addition to the Flip Focal for them to work.

I am hoping I can get a prescription where I don't have to constantly be putting on, and taking off, a pair of readers. I'm hoping I can get one pair of glasses to read and tie flies and the upper portion of the lens will have no prescription so I can leave them on.

God forbid if I can no longer tie #16 - #22 I will be very disappointed. Fortunately I have hundreds of flies that have yet to see water. In past winters I might spend an entire week tying Baetis duns and emergers in #18 - #22. Then the next week Ep. dorothea duns and emergers and so on and so forth. Without any exaggeration I am quite sure I have enough unused flies to last the rest of my lifetime. But it is still a pleasure to tie and keeps me from getting bored over the long winters when I don't fish.

Thank you David. You should be out fishing now. The Green drakes have to be on the BK about now. Also the lower EB should be seeing drakes now. One of my favorite places is behind the rest area on the Quickway.
