Tremulatory and Abdomen Vibration Signals Enable Communication through Air in the Stink Bug Euschistus heros
Figure 1
Spectral characteristics of tremulatory, buzzing, percussion and abdomen vibration produced signals.
(Above) Vibrational signals produced by tremulation (TR), buzzing (BZ), percussion (PER) and by vibrating the abdomen (AV) on the leaf and recorded on the stem 14–16 cm from the source. Sequence shown is 1 minute long. (Below) Frequency spectra of single tremulatory, buzzing and abdomen vibration produced pulses, and of a 10 s sequence of percussion signals.
