Karner blue butterfly reintroductions are underway in New Hampshire, Ohio, and Indiana, with the goal of reestablishing viable populations in those states.
Research on habitat management, dispersal, ant tending, and female egg. The Karner blue butterfly experienced drastic declines in the 1970s and 1980s, but The Nature Conservancy has been working for over 20 years to rebuild the habitat that these butterflies depend upon. Adult Butterfly The adult stage of the Karner Blue showcases the marvel of nature's design, particularly evident in the sexual dimorphism between males and females.
Sexual Dimorphism: Males boast a silver or dark blue dorsal side with dark margins, while females display a gray-brown to blue gradient, accented with orange bands.

The Karner blue butterfly is a small butterfly only reaching one inch long. Males are vibrant, silvery blue in color, and females are duller in appearance and are blue to grayish brown in color. Both male and female have rows of black spots, and the outer edges of each wing contains a row of metallic blue-green, orange, and black spots.
In 1992, the Karner Blue Butterfly, a subspecies of the small blue butterfly, was federally listed as an endangered species. Since then, the U.S. Fish and Wildlife Service's endangered species program has worked to identify, protect, and restore the Karner blue butterfly to prevent its extinction.
You, too, can help. Research is being conducted to develop methods of enhancing or creating habitat suitable for the Karner blue butterfly, in particular, the establishment and propagation of wild blue lupine. Methods used to establish or restore appropriate habitat conditions for blue lupine and the Karner blue include mowing and controlled burning.
