Butterfles ♥

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

Butterflies exhibit polymorphism, mimicry and aposematism. Some, like the Monarch, willmigrate over long distances. Some butterflies have evolved symbiotic and parasitic relationships with social insects such as ants. Butterflies are important economically as agents of pollination. The caterpillars of some butterflies eat harmful insects. A few species are pests because in their larval stages they can damage domestic crops or trees. Culturally, butterflies are a popular motif in the visual and literary arts.
