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.

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.

LowBudget has attached these 3 pictures to aid in identification. The message is below.
Body length (excluding tail) is 10 mm.
The coloration of the dun's wings gets left behind in its exuvia.

I had a couple of mayflies hatch in an aquarium. I had thought that I only had some stoneflies and beetle larvae in it but lo and behold.....

Any help in identifying these would be appreciated.

The larvae were collected from Trout Creek, a tributary of the West Branch of the Delaware River, located in Delaware County, New York.

Thank you

Looks like a female Ephemerella subvaria to me. Although 10mm is a little small.
