Hi Marci-

Notwithstanding Mack Beacon's "looks like" observation on his Facebook Group, I believe your images of this male imago to be of genus Hexagenia, rather than being of genus Litobrancha.

Your images could be of either Hexagenia limbata or Hexagenia rigida, as both species are known to reside in Wisconsin, and Litobrancha recurvata is not.

However, differentiating between those two species requires microscopic examination of the penes of the male imago. So, I am moving these images to their more appropriate placement in the guide.
