In Macau, adults are active from late spring to late summer and range in total length 11.5-20 mm and 2.5-5 mm in maximum width. According to Yiu (2009), in Hong Kong the larvae of this species complete their development inside dead branches of Ficus spp. trees. In Macau, adults were repeatedly found on the trunk of large F. rumphii and F. microcarpa trees on Little Taipa Hill (RP pers. obs.). Known host plants for the species include Artocarpus sp., Bauhinia sp., Ficus infectoria , Hevea brasiliensis , Mangifera indica , Mangifera sp., Morus alba and Morus sp. ( Lin and Yang 2019).
