Blue-winged Olives
Baetis

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

This looks to be either Hexagenia or Litobrancha based upon the frontal process being rounded and not forked. Probably is Hexagenia based upon where it was collected and Hexagenia being so widespread and common, but I cannot tell from the photo if the gill on the first abdominal segment is forked or single from these photos.

You're right. I can't see how I would possibly have misidentified this one, so I must have just absent-mindedly clicked it into the wrong category when I added it to the site.
