Karner Blue
Plebejus melissa samuelis (Nabokov, 1944)

New York State Distribution [-]
Currently, the only known occupied sites are clustered in Albany, Schenectady, Saratoga, and Warren Counties and represent remnants of two or three once large metapopulations. Historically there were also specimens, or at least reports from Watertown, Tonawanda, Rome, Sullivan County, and Brooklyn (Shapiro 1974).

Global Distribution [-]
The Karner Blue is currently found in Minnesota, Wisconsin, Michigan, northern Indiana, and New York. It has been extirpated from Illinois, Iowa, Ohio, Ontario, Pennsylvania, Massachusetts, New Hampshire, and Maine, but was reintroduced in New Hampshire and Ohio. It was falsely reported from North Carolina and Manitoba.
