Hexagenia bilineata

Moved from Mayflies.

Hi Lee-

Although this male imago is of genus Hexagenia, I fail to see an indication of it being A. bilineata, and believe it more likely to be either H. limbata or H. rigida, which have been traditionally been distinguished from one another by microscopic examination of the genitalia of male imagoes. For this reason, I am placing it in the Guide at genus level.
