Anarytropteris fallax

Males call at night from dense bushes, from close to the ground to about 3 m above, and are incredibly wary, jumping away at the slightest disturbance. The call is a continuous train of syllables produced at the rate of 7 syllables/s (at 25°C); mean syllable duration is 0.007308 (SD=0.0009306, n=37); the call is broad spec- trum, with most energy within 16.4–37.5 kHz (Figs. 48J–L). The call, produced by males only at night, is audible to the human ear from several meters. [1]
