Bionomics. In Taiwan, the larvae feed on several Symplocos species ( Symplocaceae ). The adults are on the wing throughout the year, at the elevations from 400–2100 m (Plate 11A–11C). There are apparently several generations a year (adults known from January to November). The larva is grayish–brown, with a long anal horn (Plate 11D).

Distribution. Mainland China (Zhejiang, Fujian, Guangdong, Yunan, Xizang) and Taiwan, Nepal, India.

Remarks. The specimens from Zhejiang, Fujian and Yunnan Provinces in China were misidentified by Chu & Wang (1993) as P. hyalinata Butler, 1885 , which is endemic to Japan. Its fully-grown larva was originally identified as Andraca bipunctata Walker , l865 and described by Sevastopulo (1939).
