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 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.

I had hoped to capture one of these alive for my Field Biology class during our field trip to the Pine River on Wednesday, but never did find one in the dip net. Last night I stretched out the 50-foot seine net that I had borrowed from my consulting firm for class on my deck to dry, as it was getting a little funky smelling. Well, somehow we had picked up a chunk of rotting wood from the stream and carried it home in the net. Then, this morning I went to pile the now dried net back into the box, and found this poor little fellow dried up next to the chunk of wood. I have been seeing adults lately on both the Rifle and Pine Rivers during my evening fishing trips. Hmmm, maybe it's time to pull one of those #6 Stimulators out of my dry fly box and give it a few tosses...

No matter how big the one you just caught is, there's always a bigger one out there somewhere...
