Au Sable River in Michigan

[mothman27]

I went on a canoe trip to the Au Sable River in Crawford Co., MI on monday and encountered three species of butterflies I have not seen before. 
Compton Tortoiseshell (Nymphalis vaualbum)
Green Comma (Polygonia faunus)
And what I believe is a very white Pieris oleracea

Love Tortoiseshells. Wish they were native to my area.
