The dark, gray-brown hindwing easily separates commoides from either Leucania multilinea or Leucania lapidaria. The dark, gray-brown hindwing easily separates commoides from either Leucania multilinea or Leucania lapidaria. Leucania comma, a European species so far known only from Newfoundland could be mistaken for commoides. However comma lacks the slanting black line arising from near the base of the lower (inner) margin. In addition the black accenting of the line line in the forewing reaches only about one-half of the way to discal dot. Leucania commoides Guenee Leucania commoides Guenee 1852 (Type) Diagnosis: A widespread species in North America. Forewing dark tan. A strong white line running from the base of the wing to the discal dot, heavily accented below with black. Discal dot followed by a short, black dash. Veins in outer third of forewing accented with dull white. A black, slanted line on the lower (inner) margin arising from near the base of the wing. Hindwing heavily and completely suffused with dark gray-brown. Distribution (See map below): Leucania commoides has a wide distribution in North America north of Mexico and seems to be completely absent only in the Pacific Coast region of the United States. Identification Quality: Excellent Habitat: Fairly general on the basis of distributional information. Foodplants: Dactylis glomerata (Orchard-grass) (Poaceae)* (Godfrey, 1972, U.S. Department of Agriculture Technical Bulletin, 1450: 51. * lab reared, possibly not a natural foodplant.
