Correction
After looking at the pattern of venation in the wings and the punctate dots on the femora of this striking specimen, I believe this is a pale morph of C. floridanus.

Callibaetis
This is a female imago. Very nice photo. I believe this is probably C. fluctuans, even though they are not supposed to have marked tails. On the other hand, there seems to be some difficulty in distinguishing fluctuans and floridanus imagos in areas where they overlap--TN in particular.
