This dun emerged from a mature nymph on my desk. Unfortunately its wings didn't perfectly dry out.

Mayfly Species Baetis brunneicolor
These are very rarely called Slate-Winged Brown Quills.
This is the largest common species of Baetis on our trout streams, and it can hatch in incredible numbers, drawing impressive rises of selective trout.
Anglers may have read in books about Baetis hiemalis, which is now a synonym of Baetis brunneicolor. It appears to have been a name for the fall-hatching brood of this species, which was reported to prefer slow water and weedy habitat instead of the gravelly riffles of the early summer brood.
