As in most Lepidoptera, the females are larger than males. The upperside of the females is uniform brownish yellow. The forewing with a small white cell spot. The upperside of the males is brownish red, with the hindwing somewhat darker than the forewing. The forewing has a small white cell spot. Adults are day fliers and are on wing from July to August in one generation per year. Adults do not feed.

Fully grown larvae pupate and overwinter in shallow underground chambers.
