 Along with the display behaviour shown by the praying mantid, flies belonging to the genus "Megaselia" also show such behaviour.Contrary to the typically female-selected mating that occurs for most organisms, these flies have females that show the display behaviour and males that choose the mate.Females have a bright orange colouring that attracts the male and also perform a series of fluttering wing movements that make the insect appear to "dance" and make the openings on their abdomens to swell in order to attract a male.
