Movie S1
3-D reconstruction of the internal organization of the tympanal organ in left tibia of a female Panacanthus pallicornis (Orthoptera: Tettigoniidae: Copiphorini). The animation highlights the morphological difference between the fluidfilled auditory vesicle and hemolymphatic channel. These two structures are clearly separated by a narrow joint.
Movie S2
Tympanal mechanics and impedance conversion in the anterior tympanic membrane of Copiphora gorgonensis (Orthoptera: Tettigoniidae: Copiphorini). The video illustrates the rocking motion of the tympanum and tympanal plate at 23kHz. Similar motion is observed at other frequencies as well.
Movie S3
Time-resolved mechanical response to 23kHz 4-cycle tone. The video illustrates a wave travelling across the transect shown in the video-feed picture. The yellow dot in the picture represents a landmark on the proximal part of the dorsal cuticle. This position is indicated in the animated longitudinal section by the vertical yellow line. Notable waves travel in direction distal to proximal.
