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

Holocentropus Caddisfly Larva Holocentropus Caddisfly Larva

Dorsal view of a Holocentropus (Polycentropodidae) Caddisfly Larva from the Yakima River in Washington

This one seems to tentatively key to Holocentropus, although I can't make out the anal spines in Couplet 7 of the Key to Genera of Polycentropodidae Larvae nor the dark bands in Couplet 4 of the Key to Genera of Polycentropodidae Larvae, making me wonder if I went wrong somewhere in keying it out. I don't see where that could have happened, though. It might also be that it's a very immature larva and doesn't possess all the identifying characteristics in the key yet. If Holocentropus is correct, then Holocentropus flavus and Holocentropus interruptus are the two likely possibilities based on range, but I was not able to find a description of their larvae.

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.

Trout get part of their appeal from the beautiful places they live. They are symbols of the wild and pristine.
These are my best photos of the idyllic rivers, streams, and lakes salmonids call home.

From the Sagavanirktok River in Alaska

Here Oksrukuyik Creek flows away from the Dalton Highway toward the pipeline. It eventually grows into one of the major rivers of the North Slope, and the main drainage to the west of the Sag, but where it crosses the road it's just a small grayling stream.

This is one of the many shallow, unnamed lakes in the Arctic coastal plain near the Dalton Highway.

This view of the pipeline, the Atigun River, and an impressive sunset/rise was one of my first views of the North Slope as I came through Atigun Pass in the middle of the night.

Two major forks of this grayling stream come together in this pretty pool.

Neversink Gorge (Wolf Brook) in New York

This little pool in update New York is enjoyed by many tourists every day, and it still holds a few trout -- stockers mostly, but you can't complain about the setting!

From Mystery Creek # 62 in New York

I spent more than an hour casting to several rising trout in this pool and caught only two. Its clear water and tricky currents harbor dozens of free-rising, usually very hard-to-catch fish.

From Enfield Creek in New York

I caught a nice brookie a few weeks earlier in this pool at the junction of a split channel in the stream. The huge fallen tree is great cover.

From the Mystery Creek # 23 in New York

I caught several wild and colorful 8-9 inch brook trout in the clear little pool below this waterfall.

From Mystery Creek # 89 in New York

For how many years, I wonder, have these huge slabs of rock sheltered wild brook trout?

From Mystery Creek # 89 in New York

Of all the pools I've fished, this one was most deserving of the colorful little brook trout it held.
