Caenurgia chloropha, or the vetch looper moth, is a small moth in the family Erebidae. It was first described by Jacob Hübner in 1818. This species is found in the southeastern United States, northern Mexico, and Cuba, with occasional individuals wandering as far north as southern Ontario. The wingspan is about 27–36 mm. There are two or more generations each year, and adults are on the wing from April to October. The larvae feed on vetch and other legumes, with full-grown caterpillars appearing from May onward.
