Macaria promiscuata "is somewhat larger, generally paler than southern examples of aemulataria from the same region, and with the markings more boldly defined, especially the intense, red-brown postmedial bands on the undersides of both wings... occurs from Maryland to Florida, and west to Illinois, Arkansas and eastern Texas." (Ferguson, 1974)
Macaria notata is larger and its wings have a whiter ground color.
