Species assiniboia (Plains Skipper - Hodges#4020.1)
Hodges Number
4020.1
Synonyms and other taxonomic changes
Formerly treated as a subspecies of Common Branded Skipper, H. comma. Differs from that species in appearance, habitat, and flight season (Layberry et al.)
Size
Wingspan 21-30 mm (Layberry et al.)
Identification
Distinguished from H. comma by paler colouration beneath and usually reduced spot band. This band can be quite distinct or nearly absent, and is usually white or pale yellow. The ranges of these species overlap in Central Saskatchewan and Manitoba. Other prairie Hesperia also have reduced spot bands below; they can be hard to distinguish, but flight time and the shade of the hindwing underside can help tell them apart. H. assiniboia has a slight greenish tint to the hind wing underside, and its flight time is most similar with the Pawnee Skipper, H. leonardus pawnee. (Layberry et al.)
Range
Northern Great Plains - Alberta, Saskatchewan, Manitoba, North Dakota, Montana.
Habitat
Short-grass prairie.
Season
Usually mid-July to early September (Layberry et al.)
Food
Prairie grasses.
