Pteronarcys californica

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.

Typical scene along MT-287 driving down the Madison River valley... flat pastures backed by dramatic mountains and weather in all directions.

The famous Three Dollar Bridge access point to the Madison River. I can't remember the last time I went to an access site and found so many other anglers in spot after spot after spot, on and on up the bank of the river. Every time I spotted likely-looking water up ahead and got closer, there was somebody standing along the bank waiting for an evening rise. Finally after 10 minutes of walking or so, I found about a 50-yard stretch to myself with some nice pocket water. I caught a few small fish and missed a couple bigger ones.

On-stream insect photos from the Madison River

We arrived at the parking lot on the Madison to find clouds of caddisflies swarming around everything, including every tree and vehicle in the parking lot.
