Most likely, Ephemera compar is an extinct species of burrowing mayfly in the family Ephemeridae. It was found in North America. Ephemera compar is known from a single specimen, collected from the "foothills of Colorado" in 1873, but despite intensive surveys of the Colorado mayflies reported in 1984, it has not been rediscovered.
