Insects may also communicate by tapping rubbing, or signalling. Firefies use flashes of light to find a mate. Each species of firefly has its own pattern of flashes. Males emt flashes in flight, and females flash beck in response. This behavior allows male fireflies to locate a mate of the proper species. However, theymust be aware of female firelies of the genus Photuris, which can mimic the flashes of other species. If a male of a different species responds to the flash of a Photuris female and attempts to mate, the female devours him. This is surely one of the most unusual behavioral adaptations in the enormously successful world of insects.
