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.

Case view of a Limnephilus (Limnephilidae) (Summer Flier Sedge) Caddisfly Larva from the Yakima River in Washington

This seems to be a young larva of Limnephilus. Although not clear in the picture, several ventral abdominal segments have chloride epithelia.

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.

Jason:

I am simply amazed at how nice the new site is. I have been a fan of your work since I found the old site several years ago. As a biology teacher, I have used your site to help students involved in a stream sampling project notice the subtle differences between different aquatic organisms and to understand what they find. As a flyfisherman, I constantly find myself referring to your website for help at the tying bench.

Congratulations on having the best aquatic insect site on the web!

Thanks,

Rick McClelland

Hi Jason,
You probably know me from other forums. Since you are not far from where I reside, I decided to join. The site looks great! with lots of good info. I'll be suggesting it to all my friends and family that enjoy fly fishing.

My best,
Mark
