Ephemerella subvaria
Anthony-

I believe this mayfly female subimago to be Ephemerella subvaria.

Lloyd Gonzales comment:
This has the overall look of a “swimmer” to me. The relatively narrow, brown-suffused wings and sharp hindwing costal angulation lead me to believe this is Ameletus. In E. subvaria, the costal crossveins in the lower portion of the forewing are obsolescent (typical of the genus).

Thanks! How does one recognize a subimago from an adult?

Primarily by the wings
Hi Anthony-

The wings if a subimago are cloudy in appearance, due to being covered with minute non-wettable hairs, whereas the wings of an imago are generally transparent.
