Butterfly evolution refers to the origin and diversification of butterflies through geologic time and over a goodly portion of the Earth's surface. The earliest butterfly fossils are from the early Cretaceous period, about 130 million years ago. Their development is closely linked to the evolution of flowering plants since both adult butterflies and caterpillars feed on flowering plants. Of the 220,000 species of Lepidoptera, about 45,000 species are butterflies, which probably evolved from moths. Butterflies are found throughout the world, except in Antarctica, and are especially numerous in the tropics; they fall into eight different families.
