Larva (zoology)
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect developmental biology, development such as insects, amphibians, or cnidarians typically have a larval phase of their Biological life cycle, life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterfly, butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Papilio'' is a genus in the swallowtail butterfly family (biology), family, Papilionidae, as well as the only representative of the tribe (biology), tribe Papilionini. The word ''papilio'' is Latin for butterfly. It includes the common yellow swallowtail (''Papilio machaon''), which is widespread in the Northern Hemisphere and the type species of the genus, as well as a number of other well-known North American species such as the western tiger swallowtail (''Papilio rutulus''). Familiar species elsewhere in the world include the Mormons (''Papilio polytes'', ''Papilio polymnestor'', ''Papilio memnon'', and ''Papilio deiphobus'') in Asia, the orchard and Ulysses swallowtails in Australia (''Papilio aegeus'', ''Papilio ulysses'', respectively) and the citrus swallowtail of Africa (''Papilio demodocus''). Older classifications of the swallowtails tended to use many rather small genera. More recent classifications have been more conservative, and as a result a number of former ge ...
