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.

fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or

This specimen seems to be of the same species as a dun I photographed which emerged from another nymph in the same sample.

This is the same specimen that I collected from a stream nearby.
Can anyone tell me the history( name basis) for this insect ?
Is it common across the country?
Thanks....
