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.

I can't tell you the genus, but I can do better than family: Tanytarsini. They're filter-feeding Chironomidae.

Not disinterested, but I don't have those intermediate taxonomic levels built into the database of this site. If I did, it would take a lot more clicks, CPU, and bandwidth to navigate from order to species or anything. That's one reason I integrated the forum with the insect section in the first place... so those extra details can be added here. :) Thanks.
