Found this in SW VA stream that's cold and clean. It was under cobbles in a lotic erosional zone, and had gills on 4 or 5 of its abdominal segments.

It's a burrowing mayfly, probably either a member of the family Ephemeridae or Potamanthidae.

Ohh, that makes sense with the 3 cerci and the "horns". The multiple tarsal claws and overall size tripped me up, but I'm glad I found one before the lab practical exam!
