Abstract
Variability in the temporal structure of the song has been investigated for the Australian bushcricket Requena verticalis (Listroscelidinae: Tettigoniinae: Orthoptera). Chirp interval and chirp duration of an individual male vary between two days. Males differ in their readiness to call. Sporadic singers sing consistently only in the presence of another calling conspecific or when acoustically stimulated, while steady singers call readily under acoustic isolation. Sporadic as well as steady singers change their chirp interval in the presence of another calling conspecific. Steady and sporadic singers are able to differentiate between 16 and 28 kHz, the two main frequency components of the song. There is evidence that the effect of the natural song on the temporal pattern of the call may be due to the 28 kHz frequency component. Individual variation in the temporal parameters is within 0.1 s, and the changes caused by acoustic stimulation are of similar magnitude. Further studies are necessary to evaluate if males and/or females uses these differences to discriminate between conspecifics.
