Thorax reddish brown. Abdomen fuscous. Forewings reddish brown suffused with purple. Numerous indistinct slightly waved oblique lines present. A dark streak found on median nervure. An oblique double line runs from apex to inner margin beyond middle, filled in with pale near apex. The area beyond it suffused with gold colour. Hindwings ochreous white, suffused with fuscous towards outer margin.[2]

Female has much more variegated forewings. A diffused chocolate patch found below middle of cell. A white streak can be seen on vein 2. Abdomen and hindwings fuscous. Larva dark violet brown with a sub-dorsal series of scarlet and yellow spots and sub-lateral white dot series. They pierce fruit (peach, loquat and citrus) to suck the juice.[3]

The larvae feed on Menispermaceae species, including Stephania japonica as well as Cissampelos and Cocculus species. This species overwinters in the larval stage in clusters of weeds and soil cracks around the host plant.[4] Some other food plants are Citrus, Dimocarpus, Ipomoea, Malus pumila, , Prunus persica, Psidium guajava, Sida, , Vitis, and .[5]
