Its wings are a pale straw colour and narrower than other relative species. A transverse, bipunctate blackish discal mark is present. There is an oblique, centrally zigzag, submarginal row of diffuse, dark patches. In the female, the hindwings are slightly darker yellower than that of male. But the male has dark greyish scaling with a dark discal spot. Larval host plants are Bambusa species.[4]
