A butterfly is a mainly day-flying insect of the order Lepidoptera, the butterflies and moths. Like other holometabolous insects, the butterfly's life cycle consists of fourparts, egg, larva, pupa and adult. Most species are diurnal. Butterflies have large, often brightly colored wings, and conspicuous, fluttering flight. Butterflies comprise the true butterflies (super-family Papilionoidea), the skippers(super-family Hesperioidea) and the moth-butterflies (super-family Hedyloidea). All the many other families within the Lepidoptera are referred to as moths.

Butterflies exhibit polymorphism, mimicry and aposematism. Some, like the Monarch, will migrate over long distances. Some butterflies have evolved symbiotic and parasitic relationships with social insects such as ants. Some species are pests because in their larval stages they can damage domestic crops or trees; however, some species are agents of pollination of some plants, and caterpillars of a few butterflies (e.g., Harvesters) eat harmful insects.
