Mulberry Wing butterfly

Hello, Here is another new butterfly for me that I saw last Saturday on the  Nothern Lancaster County, PA NABC butterfly count. We found this in a power line cut of a bottomland that was quite wet in places. The  Mulberry Wing seems to be a 'locally common' butterfly in wetlands from the discription in the book. The wing pattern is quite distinctive and should be a good aid in ID. Have a great day, Denis
