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.

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.

Jason, thanks. I did look on the site, but somehow overlooked these photos. This is helpful. I also did a general Google image search and got all sorts of colors, but most of the lighter BQ nymphs looked immature, with light wing pads. You and others responding are getting me closer to an answer about my emerger question.
