Wings are olive brown to brown with wide pinkish median bands.
Each wing has a large crescent-shaped transparent spot edged with gold. In the evening, females lay eggs on the host plant in rows of 10-20. The eggs hatch in 2-3 weeks and the young caterpillars feed in tight groups. Older caterpillars are solitary feeders. The grayish cocoons are attached to the main petiole of a leaf, and may drop to the ground if the main petiole falls off in autumn.
