CVU, HFE, HNF, HSF, MonT, SnM. Also NSW, ACT. Typically edging streams in slow- to swift-flowing, fresh, clear water to 2 m deep or in still backwaters, occasionally in swamps, at altitudes from c. 600–1400 m, mostly in montane or subalpine areas in the east, recent (post 1980) low-altitude collections at Riddells Creek and Cardinia Reservoir probably represent introduced occurrences.
