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.
