The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

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.
Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

These are usually found in slow to stagnant areas in the Russian River. They are approximately 16-20 mm long and are found in the river from June through August.

Jonathan - Are these the dragonfly naiads you saw? They vary quite a bit in coloration.

The shape is certainly right! I read your other post and I will definitely have to send you photos next season. They can change when they molt, huh? As far as spectacular color changes go, I saw an octopus go from solid slate grey to spotted all over in an instant, down in Key West when I was a kid. Of course, they have micromuscles controlling the opening and closing of pores to pigment glands, all driven by probably the most developed brain in the invertebrate world! Much as we all love insects, they're just not THAT cool...

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