The adults are primarily a dull brown. The upper aspects of the wings have small pale spots, while the undersides show gray scaling at the margins. The males lack the fold on the forewings leading edge, known as a costal fold, which in other species of butterflies contains scent scales (androconia).^[2] Hindwings may show darker banding. The wingspan is 32–38 mm. The wings are dull brown with small pale spots. Adults are on wing from June to July in one generation per year.
