Females tend to be darker than males and individuals from the western reaches of this species range tend to be brighter orange. Similar species include the Aphrodite Fritillary ( Speyeria aphrodite ), the Atlantis Fritillary ( Speyeria atlantis ) and the Northwestern Fritillary ( Speyeria hesperis ). It is distinguished from the Aphrodite and Atlantis Fritillaries by a wide light submarginal band on the hindwing and instead of black spots, black dashes form on the margins of the fore wing.
