InnoHippo SG Fireflies use their lights to attract mates. Every firefly species has its own flash pattern. The male Photinus pyralis, the most common species, flashes his yellowish light for a half a second while ascending and repeats about every seven seconds. The flightless females respond to these flashes from the ground or vegetation. The male knows a female of his species by the response time of her flash. The male then has to reach the female before another male that saw the flash, does. Then they can mate!
