本種はこれまで９～１０月頃に関東から東北地方のススキやヨシから得られている。東南アジアに広く分布し、日本では琉球列島に分布するB. striatopennatusは本種に似るが、メスはしばしば短翅型となり、オスは常に短翅型であるのに対し、本種はすべて長翅型である。本属はThrips genus-groupに含まれるが、触角第３、４節の感覚錐が棒状であることで識別できる。また、本属はすべてイネ科を寄主植物とする。

This species has hitherto been collected from Miscanthus sinensis and Phragmites communis of Kanto- and Tohoku-regions in Honshu, Japan, in September and October. B. striatopennatus, which is widely distributed in the Southeast Asia and the Ryukyu Islands, is similar to this species. However, striatopennatus female is often micropterous and male is always micropterous, whereas this species is always macropterous in both sexes. The genus Bolacothrips is a member of the Thrips genus-group but it can be distinguished from other members by the antennal segments III and IV with simple sense-cones. All members of this genus feed on Poaceae.
