The U.S. Fish and Wildlife Service announced Tuesday after that a rare butterfly, the Poweshiek skipperling, is a candidate for protection under the federal Endangered Species Act.
Poweshiek skipperling is a small butterfly that inhabits remnants of native prairies in Iowa, Minnesota, North Dakota, South Dakota and Wisconsin, and prairie fens in Michigan.
In Wisconsin, the butterfly is listed on the state endangered species list.
Wisconsinbutterflies.org shows sightings of the butterfly in Waukesha and Green Lake counties, and indicates that they have been seen in state natural areas in those two counties.
The Wisconsin DNR said that local naturalists reported them as common on prairies near Milwaukee and Racine in the early 1900s.
