Firefly, any of various soft-bodied, carnivorous, nocturnal beetles of the family Lampyridae that produce an intermittent greenish light in their abdominal organs. The light is created by the oxidation of luciferin under the influence of an enzyme, luciferase. In some species females are without wings and are known as glowworms. The lights serve to attract mates.
