本種はやや大型のアザミウマ科。本州から九州、中国に広く分布し、関東地方では５～１０月頃に主にアズマネザサなどのササ類に普通にみられる。中国で記載されたY. tianmushanensis Mirab-balou & Chen, 2012は体色が本種に似るが、後胸腹板に小棘を持つことなどで識別できる。

This is a relatively large species in the Thripidae. It is widely distributed from Honshu to Kyushu and China. In the Kanto-region of Honshu, it is commonly found on bamboos such as Pleioblastus chino. Y. tianmushanensis Mirab-balou & Chen described from China is similar to this species in coloration but it can be distinguished by the metasternum with spinula.
