This species is commonly confused with the Tawny Crescent (Phyciodes batesii), Pearl Crescent (Phyciodes tharos), and possibly subspecies, so that identification is often not possible. Males tend to have distinguishing upperside wing patterns which can make them easier to identify, but this still may not be conclusive. Refer to: http://www.projectnoah.org/spottings/848..., which has been identified by experts as a possible subspecies.
Much of northern North America - southwest to Utah. Flight: June - July. Open fields, roadsides, and woodland openings. Host Plants: Asters (Asteraceae).
