Gryllotalpa australis Erichson, 1842

Males of G. australis produce a loud calling song from specialized burrows similar to those constructed by G.vineae (Bennet-Clark, 1970). The calling song of G. australis is a loud trill produced for 20—30min at dusk on summer nights, when the soil temperature is above 15°C. At 23°C the call has a carrier frequency of 2-54 kHz and a pulse repetition frequency of about 70 Hz. [1]
