 As with many other insects , P. exclamans use sexual pheromones to attract members of the opposite sex . Researchers have attempted to determine the exact role that sexual pheromones play in sexual attraction in paper wasps . They set up a wind tunnel where males and females were exposed to a sexual pheromone wick that was isolated from males and females . These pheromones were taken by hexane extracts from wholes bodies and <unk> of unmated females . The male extracts were taken from the ectal mandibular and seventh sternal glands . It was found that the opposite sex was attracted upwind of the scent and the results were intensified when a fan was turned on . The range of the scent was found to be around 2 metres .
