The distress sound of the mother of the snake male Acanthinodera cumingii (Coleoptera, Cerambycidae)

Abstract

We report the first description and analysis of a distress stridulation emitted by a male Acanthinodera cumingii (Hope 1833), produced under the context of an indirect disturbance. We evaluated the temporal and spectral properties of the stridulation using digital processing software. The results of the variables studied indicate that the sound is in audible ranges for conspecifics and potential predators. We discuss the potential ecological significance of the use of this distress call and how it might relate to its environment.
