Body temperature and the acoustic behavior of the cicadaTibicen winnemanna (Homoptera: Cicadidae)

Tibicen winnemanna (Davis) produces a broad-band frequency- and amplitude-modulated advertisement call. Observations of the animals in the field show that the cicadas produce varied acoustic output. This work investigates the connection between the acoustic behavior of the cicada and the body temperature of the calling animal. The results show there is strong evidence to support the hypothesis that both acoustic output and song intensity are highly dependent on body temperature.
