Ephoron
Hi Carl-

They are of family Polymitarcyidae and of genus Ephoron.

Tortopsis
Received the following comments from Lloyd Gonzales this evening:

"(This is) Tortopsis. One way you can tell them apart is that the venation in Ephoron is very dense and netlike, and it has many marginal veinlets along the trailing edge of the wing. In Tortopsis, the crossveins are more spread apart and there are no marginal veinlets. The genus Tortopus was split and the new genus Tortopsis was designated by Molinari in 2010. Although the above specimen is well within the range of Tortopsis primus (the likely species), I'm not aware of any records for MN."
