Much less is known about these pheromones in aquatic systems e.g., for diving beetles. To test the use of pheromones and visual signals for mate finding by the diving beetle Rhantus suturalis (MacLeay 1825), behavioral experiments were performed using three different types of vessels containing conspecific. In experiments with non-permeable glass flasks, which did not allow the diffusion of chemical substances, males and females did not stimulate any reaction by conspecific of either sex. In experiments with opaque but water permeable vessels, and in experiments with vessels made of finely woven steel, which allowed the perception of chemical as well as optical cues, male diving beetles were significantly attracted to females. Females were attracted to other females only in the last experiment, when simultaneously perceiving chemical and optical cues. These results indicate that R. suturalis females release sex pheromones to attract mating partners, which is the first experimental demonstration of pheromones in the Dytiscidae.
