I do not know much about mayflies. Can someone help identify the type here? As specific as possible please. I was in Ladysmith VA.

Sean,

As far as I can tell it's Hexagenia limbata.

Could it be Anthopotamus (formerly Potamanthus)?

Paul,

Could be but the eyeball being dark on the bottom and lighter towards the top says Hexagenia as well as the overall coloration being darker.

Definitely Hexagenia

Ah, yes. Sitting on a dark background has likely overexposed the fly.
