White Admiral

Limenitis arthemis arthemis

This a basically a dark butterfly with wide white bands through each wing, which makes it a very unique looking butterfly and one of the easiest butterflies to identify. This subspecies is mainly a northern butterfly, while the Red-spotted Purple is a southern species. Nevertheless, the White Admiral has been found as far south as Illinois. It is fairly common in central Wisconsin, but I was amazed to find it in abundance in Douglas County, far greater than I expected, with easily over one hundred seen in a single day. Most of these were seen getting nutrients on dung.
