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.

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.

This is a really deep hole on a famous Catskill river.

I missed one strike in this pool after taking the picture. It was a good fish that first showed itself with a telltale bulge and eddies below my fly, the sign of a nice trout refusing without quite breaking the surface. Five or ten drifts later it took convincingly, but I missed the hookset. That was the story that day -- missed hooksets. I didn't stay to fish this pool very long, because I tried to cross to fish it from the side that's on the right in the picture, obviously the best angle, and I found that what looked like an easy crossing near the tail was a swift, bouldery flat of very deceptive depth in the clear water. I found myself half-way across, past what had originally looked like the deepest water, only to find that the water that looked easiest was even swifter and deeper. I thought surely I was in for a swim, but somehow I made it back to the near bank dry and jumped in the car to head for less treacherous wading.

This is my favorite mayfly from 2004, and it appears on my popular Be the Trout: Eat Mayflies products. Check them out!

Its identification is really up in the air. It might be a late-season vitreus dun but it may very well be one of the more obscure species in that genus.

This little gal is of the usual size for Baetid mayflies, around size 20. She came with two tails, but it's kind of hard to transport size 20 mayflies without a little bit of damage.
