General Description

Superficially similar to the other checkered skippers; The Grizzled Skipper is larger than the rare Small Checkered Skipper (P. scriptura, wingspan 16 - 25 mm) which is known only from the Milk River valley of extreme southern Alberta. Compared to the Common Checkered Skipper (P. communis), the Grizzled has less extensive white markings. The Grizzled Skipper is most likely to be confused with the Two-banded Checkered Skipper in the Mountains. To separate these two, look at the upperside hindwing spots: centaureae has poorly defined, smudged white spots, while ruralis has two rows of sharply outlined white spots. P. ruralis is also slightly smaller, and is usually restricted to low-elevation, dry montane habitats.  Subspecies freija of the boreal region is darker than the mountain subspecies (loki); These taxa may in fact be separate species.
