Rhipicera

Rhipicera is a genus of beetle belonging to the family Rhipiceridae. The larvae are parasitoids of cicadas.

The sexual dimorphism between male and female beetles in the genus Rhipicera has been attributed to using scent in mating behaviors. The antennae of males and females differ in that the males have lamellate antennae while the females' antennae are significantly smaller in comparison. It is thought that the males use their lamellate antennae, more specifically, the sensilla placodea, to detect pheromones that are produced by females. This is suggested by certain mating behaviors, such as distinct flying patterns that have been seen in other species that rely on pheromone tracking. Additionally, there have been observations of multiple adult males trying to mate with a singular female, which is seen in other species and this further supports that pheromones are used to help facilitate mating behaviors.
