The obscure sphinx (''Erinnyis obscura'') is a moth of the Sphingidae family. It lives from the northern part of South America up to the central United States. The wingspan is 56–65 mm. Females have almost uniformly grey forewings with black markings on the basal half and near the center of the costa, although some are nearly all black. The upperside of the male forewing is pale gray with black markings and a black line in the center running from the base to about three-fourths of the wing length. In both sexes, the hindwing upperside is orange with a narrow black border. Adults are on wing year round in the tropics, southern Florida and southern Texas. The caterpillars feed on various members of the Apocynaceae family, including ''Rauvolfia ligustrina'', ''Rauvolfia tetraphylla'', *''Stemmadenia obovata'', ''Philibertia'', ''Cynanchum'' and ''Carica papaya'' as well as Asclepiadaceae and spurge species, including ''Blepharodon mucronatum'', White vine (''Sarcostemma clausum'') and ''Morrenia odorata''. ==Subspecies== *''Erinnyis obscura obscura'' (tropical and subtropical lowlands from Uruguay west to Bolivia and Argentina and north through Central America, Mexico, and the West Indies to Florida, Mississippi, Texas, New Mexico, Arizona, and southern California.
