[2] The species was described from a holotype female collected by Dr Philip Jackson Darlington Jr. at the Mundaring Weir near Perth in southwestern Australia, as part of the Harvard Australian Expedition (1931–1932).

As with many other small (< 3 cm) Crinia species across Australia, rattling froglets show considerable variation in dorsal and ventral colouration and patterns.

Rattling froglets typically breed in creeks, swamps or pools, including flooded or seasonally inundated grasslands or shrubby areas beside streams, gutters and seeps.

Eggs are laid singly, usually attached in small groups or rows along stems of submerged vegetation or leaves, or on the substrate in shallow water.

Rattling froglets are common within the Perth metropolitan area, including many urban drainage lines and seemingly isolated wetlands.
