これまで本州から得られている。本種の寄主植物はネムノキで、成虫は６～８月に葉に幼虫と共に発生するが、春先にもイネ科で成虫が採集される。本種はインドに分布するR. jasminae Bhatti、R. pardus (Bhatti)に似るが、腹部第２背板側縁の刺毛が本種では４本だが、後２種では３本であることで識別できる。オスは未知。

This species has been hitherto collected from Honshu, Japan. Many adults occur on the leaves of Albizia julibrissin together with larvae in Jun to August, but a few adults are also collected from Poaceae during early spring. This species is similar to two Indian species, R. jasminae Bhatti and R. pardus (Bhatti). However, it can be distinguished from them by having the abdominal tergite II with 4 lateral marginal setae (vs. 3 setae in two Indian species). Male is unknown.
