| Abstract: | ABSTRACT This paper focuses on sound production in the larvae of Geotrupes spiniger (Marsham) (Coleoptera: Geotrupidae). A single stridulatory apparatus was identified and then analysed from a structural point of view. Sound was studied using spectography and results included a quantitative analysis with characterizing physical parameters. Results highlight the need to study stridulation in Geotrupidae more in detail, to improve our understanding of its evolutionary and biological meaning. |
