Insects make up more than two-thirds of all extant animal species, and most insect species use sex for reproduction. Many species have sexual dimorphism. Insects have diverse mating strategies. Some of them make dance-like movements, while others may use sounds and chemical substances to attract their mating partners. The photo shows insects, probably beetles mating on a liatris flower head. Liatris (common names: Blazing-star, Gay-feather or Button snakeroot) is a genus of flowering perennial plants in the Asteraceae family, found in North America and the Bahamas. Their flowers are used as a popular summer flowers for bouquets.
