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.

These are quite popular mayfly (baetis) patterns because they sink quickly due to the two beads. Where I was fishing on the Animas, the water was very murky, and I had to get deep to reach them. The trout were looking for mayfly nymphs, and this worked great. Also the flashabou back really adds to the flash and noticeability of this fly.
