Devoting his life to the study of insects, Harley Hudson discovered that their proportionately great strength, leaping ability, and other powers derived from "wonderful muscular coordination."
Mastering this talent himself, he decided to use it fighting crime. He chose the secret identity of The Firefly when his lab lights failed and he happened to notice some fireflies flickering. Among his most nefarious foes are a mad doctor known as the Cat; the Shark Man; the Mummy; and the Pied Piper.
