Red Spotted Admiral Butterfly ~ Limenitis arthemis
Here in central Minnesota, we are in a hybridization zone of two subspecies of the Red Spotted Admiral butterfly. The White Admiral (Limenitis arthemis arthemis) and the Red-Spotted Purple (Limenitis arthemis astyanax). "In the blend zone, all possible combinations of the traits of the two subspecies can be found." (Butterflies Through Binoculars, The East)
Another hybridization of the two subspecies photographed a couple of years ago.

The hybridization zone stretches "from southern Maine south to Connecticut, and in the mountains of Maryland, and west to southern Minnesota. (Butterflies Through Binoculars, The East)
