The genus Ayyaria contains this species only. This species has been hitherto recorded from Honshu (Kanto- and Chugoku-areas) and Okinawa in Japan, and is also widely distributed in the Oriental region and Australia. It feeds on mainly Fabaceae such as soybean and groundnut (Miyazaki et al., 1984). In Japan, it is also collected from Phaseolus vulgaris and Glycine soja, but sometimes collected from some plants other than Fabaceae such as Mallotus japonicus and Ipomoea nil.
