The wingspan is about 70 mm. Adults have black wings with blue spots. They are grey with black bands between segments and orange lateral lines and a black head with white markings. Adults have been observed scratching the leaves of Heliotropium amplexicaule and Parsonia straminea, possibly to suck out moisture.[2]

The larvae feed on a wide range of plants including Parsonsia (including Parsonsia straminea and Parsonsia velutina), Heterostemma papuana, Heterostemma acuminatum, Hoya australis, Leichardtia, Marsdenia (including Marsdenia velutina), Secanome carnosum, Secamone elliptica, Tylophora, Cryptostegia grandiflora, Cynanchum carnosum, and Cynanchum leptolepis.
