Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

This specimen keys pretty easily to Onocosmoecus, and it closely resembles a specimen from Alaska which caddis expert Dave Ruiter recognized as this genus. As with that specimen, the only species in the genus documented in this area is Onocosmoecus unicolor, but Dave suggested for that specimen that there might be multiple not-yet-distinguished species under the unicolor umbrella and it would be best to stick with the genus-level ID. I'm doing the same for this one.
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 still haven't got my good camera gear set up, but I wanted to get my first Alaskan bug specimen online, so I photographed this one with my point+shoot in the raft.

I would like to thank you for taking the time to photograph and post these beautiful pictures. I'm 64 years old, and an avid fly fisherman. My new hobbie is taking pics of mayflies, and I'm getting excited. I've got a new tripod on order, and an excellent camera. I would find it a pleasure to share my photo's with everyone.

Welcome. Would LOVE to see what your photos. I use photos for reference in tying mostly. But images like Jason's doddsi are just nice to see and make me appreciate the world all the more.
