Fig. 9. Comparison of the resonances of a left fore-wing of Teleogryllus oceanicus when driven by the vibration probe applied either at the plectrum or on the anal area. (A) Waveforms of the sounds produced by 10-ms duration tone-bursts at the resonant frequency: red, when driven at the plectrum; blue, when driven at the same frequency on the anal area. The quality factor (Q) of the decays of the vibration are similar. (B) Detail of A showing the region in the black box on an expanded time-scale to show the relative phase of the vibration when driven at the two positions.
