Living in a high-noise environment, the species uses "semaphoring" to supplement acoustic signalling.〔〔 ==Behaviour== ''Hylodes asper'' are diurnal. Males use both visual and acoustic signalling to attract females and to maintain their territories. "Foot-flagging" is the most distinctive visual display, usually performed while calling. In foot-flagging, the raises one hind limb and extends it up and back, exposing the silvery colour of the dorsal surfaces of toes and toe fringes.〔 Male ''Hylodes asper'' have been observed to construct an underwater chamber, apparently for use as a nest for reproduction.〔
