The bushcricket Pantecphylus cerambycinus has two types of stridulatory mechanisms and acoustical signals. The elytro‐elytral mechanism typical for tettigonioid bushcrickets is used to produce a narrow‐band calling song (peak frequency 15 kHz). An abdomino‐alary mechanism is used for disturbance stridulation. Its stridulatory file is situated on the hind edge of the abdominal tergites and consists of 50‐70 parallel ridges, covering the whole width of the tergite. The broad‐band sound (peak frequency 10 kHz) is produced by the contact between the file and ribs situated on the upper side of the hindwings which are folded in such a way that their upper side is directed toward the tergites. Defensive stridulation in bushcrickets is reviewed here, and its function and evolution discussed in the context of predator avoidance strategies. © 1996 Wiley‐Liss, Inc.
