Marine Blue (Leptotes marina)

Note the dark spots on the margin of the hindwing. These blues seldom showed the dorsal side of their wings, but the underside is well marked with wavy brown and white stripes. This species is widespread in North America particularly in the West but also ranges south into Central America. Two subspecies are sometimes recognized with Arizona specimens attributed to "L. m. reakirtii." The similar Cassius Blue (L. cassius) replaces it in the Southeastern U.S. to South America.
