Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers, and the most recent analyses suggest it also contains the moth-butterflies. Butterfly fossils date to the Paleocene, about 56 million years ago.
