The Sun Dial Lupine (Lupinus perennis) is the only host plant for the Karner Blue butterfly caterpillar. Habitat loss has led to the decline in plants, and put the Karner Blue on the endangered species list. At Wild River State Park efforts have been made to increase the Lupine population, as Karner Blues have been seen just across the St. Croix River in Wisconsin. I wish them success.
