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.
