Echinargus isola
Reakirt's Blue
Echinargus isola, commonly known as Reakirt's Blue, is a small butterfly in the family Lycaenidae. The species is native to Central America and the extreme southern United States, with regular northward migrations throughout most of the U.S. reaching nearly to the Canadian border. It has been documented visiting flowers of White Prairie Clover (Dalea candida) in Colorado, where multiple individuals may congregate on single blossoms. Very rare vagrant records extend into the southern prairies of Canada.
