Bioacoustics of Yoyetta darug

Distribution, habitat and seasonality . Restricted to central eastern New South Wales , where it is known subcoastally from around Illawarra and Burragorang regions, north to the Hunter River area ( Fig. 1 ). It is most prevalent in Greater Western Sydney. Adults occur in open forest, mainly on rough-barked eucalypts, especially ironbarks ( Eucalyptus siderophyloia , E. fibrosa in Western Sydney and E. crebra around Parramatta and the Hills District) and stringybarks (e.g. Eucalyptus obliqua ) ( Figs. 2A–B ). Females actively fly to ironbarks and secrete themselves vertically along the grooves in the rough bark on the main trunk at around 2–5 m , from which they wingflick to attract males (two mating couples were captured in these grooves). In this position they are extremely well camouflaged and difficult to dislodge when attempts are made by human observers to capture them using a longhandled net. Males fly to the locations of the females and continuously move, tick and buzz, leaving if no further encouragement occurs. Males respond to simulated wing-flicks (e.g. finger snapping) and playback of their song recordings, but are quite wary. This species has been encountered from late October to early February and co-occurs with several related and similar looking Yoyetta species , including Yoyetta humphreyae , Yoyetta repetens and Yoyetta cumberlandi .
