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 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.

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.

Went to the Neversink today and saw a lot of caddis around , size 18-20. Is this Chimarra?

Thanks

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

there is no way from that pic to determine if that is Chimarra or not. There are lots of small dark caddis in various families - Rhyacophilidae, Glossosomatidae, Hydroptilidae, Philopotamidae, Helicopsychidae, Apananiidae, etc.
