Many dozens of species of firefly are found around the world. The light that fireflies produce is used to communicate between the sexes of each species. The flash pattern is species specific and intended to synchronize and coordinate mating. In one case, a species of predatory firefly "fakes" the flash pattern of another species. Females of this femme fatale species wait for unwitting males of the victim species to fly in and then eat them. Mass congregations of fireflies have been documented to synchronize their flashing pattern, producing a light show that turns on and off rhymatically. Science has not yet ironed out the motives. One such annual display can be seen each year in the Great Smoky National Park in Tennessee, USA. Some species of firefly are brighter than others. Indigenous Amerindians have been documented to make small cages of palm material and capture species that produce bright light. They use the assembled fireflies to light their way on forest trails at night. This individual was photographed in Georgia, 2011.
