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).

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

The wings look clear enough, and the body dark enough this seems like a spinner to me. Great photo on this one and on the baetis posted the same time. Ah, yes, I see the other photos of thing bug labeled as spinners look the same.

Yes Lewis, as you observed, it's a spinner. Apart from the wings, take notice of its extremely long forelegs, which are a characteristic of male spinners, but not of male duns.
