Adults of Anticarsia gemmatalis Hubner, the velvetbean caterpillar, and Mocis latipes (Guenee), referred to as the "striped grass looper", exhibit similar external morphologies and are apparently sympatric in the Western Hemisphere. Intraspecific and interspecific differences in wing maculation, leg scales and spines, and genitalia are discussed, as well as differences in abdominal sterna of females. These differences are useful for species identification and for segregation of blacklight and pheromone trap catches.
