This species is known to be widely distributed in the Oriental Region and parts of the Palaearctic and Australasian Regions (Adler and Crosskey, 2018). It is characterized in the adult female and male by the hind tibia with a distinctive dark subbasal band, in the pupa by the six gill filaments which are widely divergent, and in the larva by the bold head spots.

The female is autogenous at least for the first batch of eggs (Takaoka, 1989) and the immature stages are associated with small slow-flowing streams such as irrigation channels in rice fields in lowlands, but they also have been found at high elevations (1,315–1,813m) in Cameron Highlands (Ya’cob et al., 2016b).
