Supplementary material S17: All instances of jolting pulses on honeycomb where the vibrational trace is clearly visible (spectrograms).

<p>A series of spectrograms demonstrating the most clearly visible <em>Varroa </em>jolting vibrational pulses registered on honeycomb. These spectrograms showcase the larger variation that is observed in jolting pulses on this substrate. Panels e, f and h provide evidence for the broad-band and generation of signal at the high-frequency bandwidth. The magnitude of acceleration is logarithmic (to the base 10), where the maximum is in red (1x10^-3 m/s²) and the minimum blue (and forced to be 1/20 of the maximum).</p>
