Etymologyįurther information: Taxonomy of the Lepidoptera The Smithsonian Institution says 'butterflies are certainly one of the most appealing creatures in nature'. Culturally, butterflies are a popular motif in the visual and literary arts. Larvae of a few butterflies (e.g., harvesters) eat harmful insects, and a few are predators of ants, while others live as mutualists in association with ants. Some species are pests because in their larval stages they can damage domestic crops or trees other species are agents of pollination of some plants. Many butterflies are attacked by parasites or parasitoids, including wasps, protozoans, flies, and other invertebrates, or are preyed upon by other organisms. Some, like the monarch and the painted lady, migrate over long distances. Some butterflies, especially in the tropics, have several generations in a year, while others have a single generation, and a few in cold locations may take several years to pass through their entire life cycle.īutterflies are often polymorphic, and many species make use of camouflage, mimicry, and aposematism to evade their predators. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, and after its wings have expanded and dried, it flies off. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed.

Butterfly fossils date to the Paleocene, about 56 million years ago.īutterflies have a four-stage life cycle, as like most insects they undergo complete metamorphosis. The group comprises the superfamilies Hedyloidea (moth-butterflies in the Americas) and Papilionoidea. Butterflies ( Rhopalocera) are insects that have large, often brightly coloured wings, and a conspicuous, fluttering flight.
