Poecilimon propinquus produce songs by a single closing movement of the wings. The resulting verses are short, lasting 60–140 ms in length. They are regularly repeated to form long-lasting series of up to 109 syllables per minute. Compared to the grass- hopper song, there is little modulation in either amplitude or in the frequency domain. The frequency ranges between 16 and 35 kHz, and most energy lies in the ultrasonic range (Fig. 5). ... P. propinquus is vocal strictly during the night, with an onset of singing twenty minutes after darkness. The acoustic activity increases steadily over the next 70 min and reaches a steady plateau after that time (Fig. 6).
