Tawny-Edged Skipper (Polites themistocles) lives in open grasslands across Eastern North America. It feeds on grasses and leaves.
Fascinating facts about the Tawny-Edged Skipper
- Its wingspan measures just three-quarters to one inch, or 19-25 mm, making it a small but noticeable butterfly. It inhabits a broad spectrum of environments, from alpine bogs and forest glades to grassy meadows, savannas and the edges of streams. Across its range the flight period shifts: in the north and west adults are on the wing from June to early August, in the east from May to August, and in the deep south they may be seen from May until early November.
- The male's upper wings are brown or olive-brown, highlighted by a bright orange stripe along the forewing costa that stops at the stigma, creating a vivid contrast with the darker hindwing. Females share the brown ground colour but display a much fainter orange costa on the forewing. The stark "tawny-edged" forewing colour stands out against the hindwing, a key field mark for identification.
- The forewing stigma of the tawny-edged skipper is noticeably thicker than that of the similar male crossline skipper and runs almost parallel to the costa. In contrast, the crossline skipper's male has a thinner stigma that does not follow the wing edge. This morphological detail, together with the generally smaller size of the tawny-edged skipper, provides a reliable way to separate the two species when they share habitats.
