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.

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.

Hi, I'm trying to id a fossil but since my area of expertise is not about insects I'd to know if somebody can orient in my search for the affinity of the following two mandibulate capsule-like structures. I looked at several images of similar structures and I decided that they could be chironomid head capsules, but... I don't know how to upload the images. can somebody let me know, please?
