- Chamber music: an unusual Helmholtz resonator for song amplification in a Neotropical bush-cricket (Orthoptera, Tettigoniidae)
Summary: Laser vibrometry, microcomputed tomography and finite element modelling are used to show that an unusual pronotal inflation covering the wings of a bush-cricket acts as a Helmholtz resonator.
- A novel acoustic-vibratory multimodal duet
Summary: Paleotropical false-leaf bushcrickets exhibit a novel multimodal duet with alternating male acoustic calls and female tremulation signals; this functions in mate localization and may have evolved under predator pressure.
