The ranges of humidicola and phragmatidicola do not overlap (phragmatidicola does not occur in the southeastern United States, southern Texas, or southern California). In addition Leucania phragmatidicola is a darker brown and the male lacks the heavy brush of hair on the prothoracic tibia. Leucania humidicola Guenee Leucania humidicola Guenee 1852 (Type) Cirphis februalis Hill 1924 (Type) Rest of the synonymy of this species uncertain Diagnosis: A tropical New World species reaching the extreme southern regions of the United States. Forewing light tan with a slight yellow tint. A prominent white line stretches from the base of the wing to the discal dot, the line heavily shaded below with dark brown. Postmedial line represented by a series of dark spots. Hindwing pure white with a slight amount of gray-brown suffusion along the the outer margin. Prothoracic tibia of the male with a heavy tuft of hair-like scales. Distribution: Leucania humidicola is widely distribution in the American tropics and occurs in the United States only in the south of Florida, Texas and California. Identification Quality: Excellent for the United States, but identify confused in the American tropics because of the existence of related and similar species. Habitat: Leucania humidicola is a tropical and subtropical species. There are no specific details about its habitat. Foodplants: Lolium sp., Oryza sativa (rice), Saccharum officinarum (sugarcane), Triticum aestivum (wheat), Zea mays (corn), Phalaris sp. (HOSTS, 2005, Gaden Robinson, Natural History Museum, London). The identity of humidicola in the Neotropics is hopelessly confused and this list of foodplants may not accurately reflect the food preferences of the species. Larval Description: None available.
