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.

Some characteristics from the microscope images for the tentative species id: The postero-lateral projections are found only on segment 9, not segment 8. Based on the key in Jacobus et al. (2014), it appears to key to Neoleptophlebia adoptiva or Neoleptophlebia heteronea, same as this specimen with pretty different abdominal markings. However, distinguishing between those calls for comparing the lengths of the second and third segment of the labial palp, and this one (like the other one) only seems to have two segments. So I'm stuck on them both. It's likely that the fact that they're immature nymphs stymies identification in some important way.

I realize there are many BWO variations as well as PMD's.
BUT,
In general, if a PMD spinner body is, generally speaking, a rust color, how would you describe the BWO spinner body color?
Thanks

Hi Byron-
I'd say brown, varying all the way from a light tan to blackish brown.

I agree that rust is one color of a PMD spinner but on the Western river that I fish we also see spinner bodies almost the same light greenish yellow that we see on the duns and also some that are tan. When I go out for my two week trip I have about eighteen each of rust, greenish yellow, and tan. Because you don't ever know what spinners will be on the water on any given day. Some days it is all rusty from 9:00 to 5:00 other days a mix of the greenish yellow and the tan and no rusty's. The only adult we see emerging is the PMD. There are no other apparent mayflies emerging simultaneously.

Well done, Roger. I couldn't think of one simple way to answer this, so I waited, and you did it. In the summer one stream I fish gets some size 24 or 26 tan spinners from an "olive" dun that is mustard colored. They fall right after Tricos. Cornuta spinners are often almost black. And there are a lot of bugs in sizes that fall between these.
I haven't fished out west more than once, but Matt's reply will be helpful if I get a chance to go back.

The reason I asked, is that I am using some spectrumized dubbing from Caucci's old Deleware River Club.
On the package, the color is called "charcoal" and it is blended to imitate B>W>O. (common name); E. kata (Genus/Species); stage (spinner)
This is the color of the dubbing:

Sorry, E. late.....not kata

Hi Byron-
Actually, it has been classified as Drunella lata for about 35 years. :-)

Byron, I use the DRC dubbing as well, and like it. Had good luck on Penns Creek one evening with cornuta spinners tied with a black thread body and DRC dark olive thorax. The charcoal should work well for the fly too. The thorax on these flies is especially pronounced. The folks at the DRC still don't use the new classifications, sticking with what matches Caucci's book, Hatches.

Crepuscular,
I think I have everything published by Caucci/Nastasi. They are sort of Herod to me. They consistently married a bit of science and scientific approach to fly fishing/tying.
I seem to recall, that in one of their later publications, they clarified the fact that it should have been Drunella. Drc still uses their original identification term, though.

Byron-
Authors (like Caucci & Nastasi) write books which refer to mayfly scientific names. Taxonomists often subsequently make taxonomic revisions to those scientific names. Mayfly Central periodically publishes the latest mayfly taxonomy for North America. And, I provide a service to flyfishers by publishing those taxonomic revisions which affect books in my extensive personal flyfishing entomology library, one example of which is Hatches II by Caucci & Nastasi. Hope this adequately answers your question, but if you (or others) have followup questions, I am always pleased to answer them.

OK. I had to laugh because I was typing out basically the same thing as Roger, and before I posted it and he beat me too it. I'm sorry if offended you by smiling at Roger's post.
