Blue-winged Olives

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 dun emerged from a mature nymph on my desk. Unfortunately its wings didn't perfectly dry out.
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.

A porcupine climbs a pine tree near a trout stream.
I saw this porcupine cross the road behind me while I was watching from a bridge for some large trout I'd heard about.  I ran back to the car for the camera and got quite close for a picture.  Speed is not one of the noble porcupine's many virtues.

I collected this uncooperative specimen as part of a small cloud of female spinners clustered tightly together high about 10 feet above the water, without any males that I could see.
