Eastern Pine Elfin
The Eastern Pine Elfin has been found throughout most of Wisconsin except the southeastern corner of the state. This species is found throughout the eastern United States, but becomes less common southward. The Western Pine Elfin is a very similar species that is essentially a western species, but with a scattered distribution near the Great Lakes region, and has been found in 7 counties in Michigan’s upper peninsula, one county in Minnesota, and has only recently been reported from Wisconsin. The third photo is of one nectaring on a grass, a highly unusual nectar source for any butterfly!
