Spinadis simplex
no black spots in femora removing Epeorus. it was the tight eyes that got ya. this use to be Anepeorus which is now Spinadis simplex i wish i could see the pronotum cause there is a tiny protrusion on the lateral sides. I blew up the image the pronotum projection is just barely visible. Spinadis simplex. the range is good.

Tough angle for an id
Hi Seth-

Although an excellent photo, it is a difficult angle from which to make an id of a winged mayfly. Do you have a photo which is more from the side, even if it is not as good of a photo?

Thanks,

Epeorus pleuralis
Not a problem, Seth. I was vacillating between a couple of possibilities, so I asked my for good friend and fellow aquatic entomology/taxonomy enthusiast (Kurt Schirmer) for his opinion.

Here are Kurt's comments:

Well, this has to be Epeorus pleuralis - curiously with paler legs than usual and sans the tell-tale femoral heart shaped maculations. The head is clearly heptageniid as are the two tails in this case. The solid dun wings and lack of a mesonotal suture preclude other options.
