Remarks.

In Macau, adults are active throughout the spring and summer, both during the day feeding on flowers and at night when they are attracted to artificial lights. They range in total length 10.5-13 mm and 2.5-3 mm in maximum width. There appears to be no information available in the literature on the larval food plant(s) of this species.
