Well this guy about blew my mind. No idea mayflies were in man made lakes. This bug was about 3/4 inch body length. Found yesterday, James Reed Park, cloudy, windy, 48 degrees. I have enhanced the green of the eyeballs a bit in Photoshop so they stand out, but could definitely see the color au natural.
Any help appreciated

Hi Paul-

I believe this female subimago to be Stenonema femoratum.

Also, what clued you in to this being female?

The clues to it being a female were the absence of male claspers sticking out beyond the abdomen, in combination with the smaller compound eyes characteristic of a female.
