Forewing wide and blunt, usually white but occasionally with more or less tan coloration in northeastern part of range. Female with vestigial maxillary tentacles. Comparison with similar species Similar to many species in the yuccasella complex, especially the largely sympatric yuccasella and cassandra , but females lack functional maxillary tentacles in this non-pollinating cheater species. Specimens with tan coloration are also assignable to intermedia.
Genitalic characters are also helpful in obtaining a definitive identification.

Geographic distribution Throughout the Great Plains and areas east of it, extending into central New Mexico. Habitat Natural habitats include sand dunes, pine forest and glades in the east, and grassland, shrub desert, and pinyon forest elsewhere.
