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

This one pretty clearly keys to Kogotus, but it also looks fairly different from specimens I caught in the same creek about a month later in the year. With only one species of the genus known in Washington, I'm not sure about the answer to this ID.
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.

Crane Flies

Crane Flies are most important to trout in the larval stage, especially when high water disturbs their often large, grub-like larvae into the drift. The adults are occasionally important enough to cause selective feeding, but it is a rare occurrence.


This common name refers to only one family. Click its scientific name to learn more.

True Fly Family Tipulidae

These are pretty much always called Crane Flies.
Craneflies are only occasionally important. There are rumors of fishable mating flights, but most anglers will not encounter them. The larvae are probably the most important stage in the trout's diet.
