The calling song of the cicada Beameria venosa is a continuous train of sound pulses produced at a rate of 385 ± 29.5 pulses/s, with peak energy at 16.96 ± 1.76 kHz. The long-range sound field of B. venosa is symmetrical, but modified by interaction with vegetation and wind in the environment. High frequency of the call of B. venosa has a selective advantage with respect to avoidance of predators, permitting this cicada to be unnoticed by predators, principally birds and lizards, which cannot hear the call. As a result, the predation pressure on this cicada is decreased.
