Abstract Scope |
Cicadas are renowned for their loud, species-specific songs, produced by specialized vibrating organs called tymbals. This study leveraged lab-scale x-ray microcomputed tomography (XCT) to conduct a detailed, non-destructive analysis of the 3D tymbal morphology in Neotibicen canicularis (the dog-day Cicada). XCT allowed us to visualize and quantify internal tymbal structures, including the intricate rib arrangements, underlying support structures, and the morphology of the resonant cavity in three dimensions. A multimodal analysis of the relationship among tymbal structure, material characteristics, and acoustic emission yielded an in-depth multiscale understanding of the mechanisms via which cicadas produce their distinctive noises. This data will provide valuable insights into the evolution of sound production within this diverse insect group. |
