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 species was fairly abundant in a February sample of the upper Yakima.

Male Ephemerella aurivillii Mayfly Spinner Pictures
This spinner molted from a dun after being photographed, and the dun form is listed here as a separate specimen. I've rarely found a more cooperative and photogenic mayfly.
This mayfly was collected from Nome Creek in Alaska on July 10th, 2011 and added to Troutnut.com by Troutnut on July 16th, 2011.

Gotta love Ephemerella spinners! I was thrilled that this one emerged and molted intact, and then behaved so well in front of the camera.
