Movie 3.

Vibration maps at four resonant frequencies of a P. gorochovi male left wing as recorded with LDV. Vibration maps show complete-cycle vibrations at 4, 9.8, 13 and 17.1 kHz, corresponding to the vibration velocity peaks seen in V1 (lower right graph) and Fig. 3A. Vibration amplitudes are normalised; dark blue depicts the lowest negative vibration velocities, dark red the highest positive velocities.
