Kogotus Stonefly Nymph Kogotus Stonefly Nymph

Dorsal view of a Kogotus (Perlodidae) Stonefly Nymph from Mystery Creek #199 in Washington

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.

Trout, Salmon, and Grayling

Salmonids large and small rank among nature's most pleasing sights. These are my best pictures of trout and their relatives: salmon, grayling, and whitefish.

This big old brown trout took a dry fly and fought like he looks like he would.

This bruiser was perhaps the largest cutthroat I've ever caught to date, at 21.5" with a 12.5" girth.

This Golden Trout was probably the most vivid fish I've ever caught.

A really pretty Goldbow (Golden Trout x Rainbow Trout hybrid)

Characteristically beautiful wild-born Golden Trout from an unnamed tarn high in the Rocky Mountains.

This nice-sized Yellowstone cutthroat took a tight-lined nymph in fast water.

This was my personal best Westslope Cutthroat to date, 18 inches and shaped like a football. The fight was great fun, standing on a boulder over deep water with no waders as the fish tore around in the fast water.

Pretty pastel colors on the side of this little Bonneville Cutthroat that still has its parr marks.
