Synonyms and other taxonomic changes
Eumorpha fasciata
Identification
Strong white bands on wings. Brown band on costa (leading edge of forewing) distinguishes from the similar, less widespread, Vine Sphinx, E. vitis.
Caterpillars highly variable. Black spiracles edged with white, and diagonal white stripes pointing towards the head (much less common than the reverse, in sphingids) seem to be common features. One caterpillar form is mostly green. Another form has a base color of green or yellow, pinkish-red and black cross-stripes, red feet and longitutudinal sub-spiracular green or yellow stripes edged with red.
Range
Southeastern United States into tropics. Strays (temporary colonization?) northward.
Habitat
Old fields, nearby woodlands with hostplant
Season
May-July, August-November (2 broods) in southern US. Only latter brood farther north.
Life Cycle
Larvae feed on Evening Primrose, Oenothera species, Water Primrose, Ludwigia species, and other related plants (Onagraceae).
