Erinnyis obscura (obscure sphinx) is a moth of the family Sphingidae. 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.
