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 one seems to tentatively key to Holocentropus, although I can't make out the anal spines in Couplet 7 of the Key to Genera of Polycentropodidae Larvae nor the dark bands in Couplet 4 of the Key to Genera of Polycentropodidae Larvae, making me wonder if I went wrong somewhere in keying it out. I don't see where that could have happened, though. It might also be that it's a very immature larva and doesn't possess all the identifying characteristics in the key yet. If Holocentropus is correct, then Holocentropus flavus and Holocentropus interruptus are the two likely possibilities based on range, but I was not able to find a description of their larvae.
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.

Biography & Thoughts
Hello! My name is Daniel and I am a HS biology/anatomy teacher and debate coach during the school year, and a Fly Fishing guide for "Solitary Angler" in the summers. I am lucky to call Wyoming's Green, Hams Fork, Fontenelle and Smiths Fork rivers home. I also fool around on Lake Flaming Gorge some. My wife knows how to sling line too, and together we feel very lucky to be raising our kids here!

I grew up fishing the waters of Minnesota for the standard warm water species and played as often as I could on the North Shore of Superior with trout/salmon/steelies. I did my undergrad work in Iowa (where I chased fish on the Cedar River, hunted upland birds and waterfowl, and missed way to much class), did a 4-year stint teaching in Chicago and getting grad school done (fishing on park ponds and Lake Michigan saved my sanity). In the summers during this phase of life I spent 9 seasons guiding young fishermen in the Black Hills at a youth camp.

Wanting to be out west again and out of the city, I finally landed my current teaching position in Wyoming (more than 20 years ago now) where I float my beloved Green River south of Pinedale Wy as often as I can. I also hunt waterfowl & grouse (I'm a bird dog guy), elk, deer, and antelope (archery and rifle). I camp, backpack, and mountain bike too - but its all about getting into the backcountry to fish and hunt.

This is my 24th year of teaching and coaching debate. I deeply love what I do. Teaching is good for my heart. Debate is good for my mind. Fishing is good for my soul.

My wife and I have been married almost 5 years. She is my best friend. Together we have 4 kids; a 10-year old daughter, 2 17-year old boys, and a 20-year old daughter in college. Our house is full of life with all the kids and pets and activities.

It is a good life. Better than I deserve, more than I hoped for, and one I do not take for granted.
