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).

Nice flies, Mark; thanks for sharing...
Casey, my guess is that the flies are laid on their sides on a blotter board and shot from above using a macro-telephoto. Even under the "normal" flash settings, with a macro-telephoto, the depth of field becomes extremely shallow. Since Mark does use soft hackles (I assume) getting the flies straight is much easier.

Eventually, all things merge into one...and a river runs through it.
