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 wild-looking little thing completely puzzled me. At first I was thinking beetle or month larva, until I got a look at the pictures on the computer screen. I made a couple of incorrect guesses before entomologist Greg Courtney pointed me in the right direction with Psychodidae. He suggested a possible genus of Thornburghiella, but could not rule out some other members of the tribe Pericomini.

I have been receiving decent action in the slower deep runs they are very very tenative still. I have also pulled some out of the well oxygenated plunge pools. Flies of choice have been the #22 Mercury RS2, #20 Mercury Blood Mige, #22-24 Mercury Brassie, #22-26 Black Beauty, #22-24 Mercury Midge. The flows are gradually showing an increase in flow along the entire drainage. With all the snow we got so far this year it looks like it will be another great year of trout hunting in Colorado.
