Bionomics. Symplocos chinensis (Lour.) Druce, 1917 (Symplocaceae) is the recorded larval host in China by Chu & Wang L.Y. (1993), who reported the species Prismosticta microprisma as a misidentification of the species P. t i re t t a Swinhoe, 1903 in their paper. Zolotuhin & Tran (2011) recorded the Eurya sp. ( Theaceae) as its host in Vietnam.
