Red Spotted Admiral Butterfly ~ Limenitis arthemis

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)

I saw one of these hybrids in our yard yesterday pictured in the first photo. This butterfly could be classified as the Red Spotted Purple except for the two white spots on the outer front wings.

Another hybridization of the two subspecies photographed a couple of years ago.
The White Admiral has a broad white band and is darker in color. This butterfly was photographed in the Boundary Waters near the Canadian border.

The major native foodplant for the White Admiral is Birch and Poplar trees and the Red Spotted Purple prefers Cherry trees.

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)
