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 resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive ID.

Just for the sake of discussion. Is (the link above) the Baetis nymph we're imitating in PA right now? If so, would you consider the abdomen color a medium olive and the thorax a darker olive. I was turning over rocks yesterday on Spring Creek and the nymphs appeared to be a lighter color than my dubbing mix. I catch fish with them, but I'm always trying to improve. I may be mixing mine too dark.
I use the Flyfisher's Paradise recipe:
40% Dark Brown Rabbit (Hareline #24);
40% Black Rabbit (Hareline #7);
and 20% Olive Sparkle Yarn

Bruce, I think Steve made this up to represent nymphs right at the time of emergence, when they darken, though I suspect that nymphs often vary some in color. I have some of the FFP recipe dubbing and have used it a bit, but mostly tend to tie my baetis nymphs lighter and more olive.
