Heptageniidae
Hi remmahk-

To my knowledge, the only current (or former) species of Heptagenia found in KY are Heptagenia flavescens, Heptagenia marginalis,and Raptoheptagenia cruentata, none of which have those distinct tail markings. So, I am placing your images at family level in the guide with the hope that someone will eventually be able to identify them to a lower level.

 
Thank You
Very much appreciated!
