Sexual calling behaviour, and the effects of immediate mating history and consexual presence in the seven‐spot ladybird, Coccinella septempunctata

open access: yesEntomologia Experimentalis et Applicata, Volume 173, Issue 5, Page 393-402, May 2025.
To attract mates, several coleopteran taxa release volatile sex pheromones via a behaviour termed calling. We studied a postulated calling behaviour in the seven‐spot ladybird Coccinella septempunctata L. for the first time. We also investigated the effects of immediate mating history and the presence of conspecifics on calling behaviour.
