Wing span: 2.5 cm.
Flight time: Apparently double-brooded, with the first flight occurring from late April to early June, and the second from early July through early August. Bivoltine populations have previously been only reported from Illinois and the Delaware River south (Opler and Krizek 1984).
Status: Infrequent breeding resident.
Distinguishing features: This species is small and dark with checkered edges and a violet overscaling on the hindwing below.
Distribution and habitat: The Roadside Skipper is limited to the southern third of Iowa, with populations extending north along the Loess Hills and the Mississippi River. It is restricted to xeric prairie habitats, including Loess Hill prairie, sand prairie, and limestone and sandstone glades.
Natural History: The Roadside Skipper overwinters in the pupal stage. While its larvae have been reported elsewhere to consume a wide variety of weedy grasses, its limitation to high quality prairies suggests that this is not the case in Iowa.
