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 is the first of it's family I've seen, collected from a tiny, fishless stream in the Cascades. The three species of this genus all live in the Northwest and are predators that primarily eat stonefly nymphs Merritt R.W., Cummins, K.W., and Berg, M.B. (2019).

thanks roger, bwo patterns were the closest i had but they werent producing. looking at the picture now a light bodied fly may have been better as the underside of the abdomen appears to be pretty light colored.
we seek for slumbering trout,and whispering in their ears,
give them unquiet dreams.
