Mayfly - Hexagenia Mayfly - Hexagenia - female

Moved from Mayflies.

Hi Ilona-

I believe this female subimago to be either Hexagenia limbata or Hexagenia rigida, both of which are known to reside in Wisconsin, but require microscopic examination of the male imago genitalia in order to differentiate from one another.

Moved from Hexagenia.

If you're hoping for a species ID...
...please move the pics to Ephemeroptera. Roger doesn't review images posted deeper in the Guide.
