General Description

A large (5.5 – 7.5 cm wingspan) heavy-bodied skipper. The dorsal wing surfaces are brownish black with white fringes and a series of pale marginal spots. Males are smaller and darker than females. Males have a series of six prominent white or pale tan spots on the outer costa and margin of the forewings, and a narrow yellow tan marginal band on the hindwings. Females have larger paler forewing spots which usually form a continuous band, and usually one or more pale spots on the hingwing in addition to the pale marginal band. In both sexes the ventral surfaces of the forewings are similar to the dorsal surfaces, but the hindwings are heavily dusted or frosted with pale scales and have several small white spots. This large skipper is unlikely to be mistaken for any other Alberta lepidopteran.
