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).
I fish primarily the creeks filled with brook trout and cutthroat, but will fish the larger waters at times for browns and rainbows. I fish the old traditional ways of dry fly and spiders, casting upstream like it is meant to be. I tried using nymphs and found it to be not as challenging as I personally would like. Too effective.
