Wing resonance in S. piercei as measured with Laser Doppler Vibrometry.

Scanned area and defection shapes of the right wing (RW). A and B show the orientation image relating wing topology to the position of the scanning latice. (C, D) Area scans of mirror deflection at best response (122 kHz in this species). Wings scanned in normal position close to the body. Note how the mirror membrane strongly deflects while the rest of the wing veins and folded membranes rest in position. (E) Displacement and resonances of the left wing (LW) and RW. (F) Phase gain response of RW vibration. (G) Coherence across the frequency range measured for the RW response. (H) Expected and observed radiator size optimal for the frequencies used by Supersonus spp.
