Blue-winged Olives
Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

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

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.

Like minnows, crayfish are an extremely important food source for large trout. Many feed on nothing else for weeks at a time. Anglers are perpetually on the search for the perfect crayfish imitation, and so far no fly tyer outside the realm of rumor and legend has devised one.
