Sci News – A Flash of Love Light
Some guys really light up when trying to get girls’ attention. Especially if they’re fireflies. But according to a recent report in the journal Science, males of the Photinus carolinus species have upped their game. Rather than each flashing separately, a swarm all flash together to improve their chances of getting female attention. When scientists exposed female fireflies of the species to LED signals that mimicked males’ signals, females responded best to flashes that were perfectly synced, while those that were totally out of sync received only a 10% response rate. The scientists believe that flashing en masse, well, outshines other species’ signals and so sends females a clear message that their male mates are around. This probably gives the species an evolutionary advantage. Unity is strength they say.
