Wisconsin's Threatened & Endangered Butterflies & Moths

Wisconsin currently has seven species of butterflies and moths that are threatened (THR) or endangered (END) with extinction, including one threatened species (the Frosted Elfin) and six endangered species. These species are distributed in different parts of the state, and their habitats can vary widely. Many butterflies and moths tend to prefer prairie habitats; however, the frosted elfin prefers dry oak / pine forests, the phlox moth prefers pine and oak barrens, and the swamp metalmark prefers alkaline wetlands (fens), all of which are rare communities. Thus, care must be taken in the protection of all of these natural communities and habitats.
