Nemoria zygotaria appears to be a species unique to Texas in the US, though it is relatively common in south central Texas and has been collected over a wide range of counties in that region. Ferguson (1985) reported adult specimens were known from every month of the year except August and December. The geographic range of zygotaria coupled with its distinctive abdominal color and wing markings make it a readily recognizable Nemoria species. White am and pm lines are quite thin on a bright green wing ground color, sometimes with fine white striations as seen on the specimens above. The wings have green fringes with a white outer margin and a white basal costa with no terminal line on the wing margins or other red markings. The interantennal fillet is pure white. The abdomen is green on the dorsal surface and notably lacks any additional spots or marking. Ferguson reported that the genitalia of Nemoria zygotaria closely resemble those of Nemoria bistriaria, and he grouped it with the bistriaria species complex.
