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 specimen keys to the Epeorus albertae group of species. Of the five species in that group, the two known in Washington state are Epeorus albertae and Epeorus dulciana. Of the two, albertae has been collected in vastly more locations in Washington than dulciana, suggesting it is far more common. On that basis alone I'm tentatively putting this nymph in albertae, with the large caveat that there's no real information to rule out dulciana.

After years of pursuing trout I thought I knew a lot about their behavior. After being proven wrong a few times it seems that I don't know as much as I thought I did.
So with that in mind could someone suggest a good book about trout behavior? Especially in western rivers like Deschutes or Metolius.
Thanks in advance

Haven't read Understanding Trout Behavior, as I'm more interested in aquatic insect behavior, but it sounds like what you are seeking.

Having heard good things about the video "The Underwater World of Trout," I've put it in my Netflix queue. I'll try to remember to let you know what you think when it arrives.

Hi Stew,
First, I've not read the book that was suggested. It sounds interesting. I think trout are creatures that react to a stimulus and to genetic characteristics that are built into them. I always thought that Cecil Heacox's THE COMPLETE BROWN TROUT was a very good book for getting to know these characteristics. However, I've been fishing for trout for over 45 years, and the conclusion I've come to is unless you ARE A TROUT, you will have great difficulty understanding their behavior at times, and that, to me, is what makes it interesting. However, with that said, we have to keep trying to understand it, and again, that's what makes it interesting.

I'm not sure what level of information you are seeking, but if you haven't read Tom Rosenbauer's Reading Trout Streams (Nick Lyons Books, 1988), I highly recommend it. Although it is not a scholarly tome (at scarcely more than 150 pages), his analysis is based on very solid behavioral understanding and research as well as experience. I've yet to find anyone who didn't find the insights and observations in that book to be practical and valuable.
