The Endangered Karner Blue Butterfly
(Lycaeides melissa samuelis)

Karner blues historically were found in 12 northern states and in Ontario, Canada. They now can be found only in Indiana, Michigan, Minnesota, New Hampshire, Ohio, New York, and Wisconsin.

Like most endangered butterflies, Karner blues are victims of industrial and agricultural development. The Karner blue butterfly must lay its eggs on wild lupine plants (Lupinus perennis) because that is the only plant the hatched larvae can eat.

The lupine can only thrive in pine barrens with dry sandy and acidic soil, but those habitats have largely been destroyed.  Now the lupine itself is endangered and without it, the Karner blue larvae cannot survive.
