A Nymphalidae with an orange background and black spots. The wing outline is quite jagged. The wing margins are slightly lighter in color. There are a summer type and an autumn type, and the summer type is pale and yellowish, while the autumn type is bright orange. The underside of the wings, like many other Nymphalids, has a protective, dead-leaf-like coloration. The hind wings have a small white "C" pattern.

The larvae eat grass, and can grow in almost any environment where it can grow.

It was taken in the grasslands in Hachioji city. It sucks nectar from flowers while flying near the ground. I observed several individuals, and all of them looked like summer type from the color of their wings, but their wings were already tattered.
