From Wikipedia, the free encyclopedia


A butterfly is an insect of the order Lepidoptera, and belongs to one of the superfamilies Hesperioidea (the skippers) or Papilionoidea (all other butterflies). Some authors have also suggested the inclusion of the superfamily Hedyloidea, the American butterfly moths.[1] They are notable for their unusual life cycle with a larval caterpillar stage, an inert pupal stage and a spectacular metamorphosis into their familiar and colourful winged adult forms. The diverse patterns formed by their brightly coloured wings and their erratic-yet-graceful flight have made butterfly watching a popular hobby.


The Old English word for butterfly was buttorfleoge apparently because butterflies were thought to steal milk. A similar word occurs in Dutch and German originating from the same belief. This is believed to have led to the evolution of its present name form - butterfly.[2]

An alternative folk etymology, prevalent in Great Britain, is that it originated as a contraction of butter-coloured fly referring to the Brimstone Butterfly Gonepteryx rhamni, often the first butterfly of spring. Another such view is that the word butterfly came from a metathesis of "flutterby".

Origin and distribution

Butterflies are believed to have evolved from a branch of ancestral forms of moths. This branching is believed to have happened in the Cretaceous Period, 65 million to 135 million years ago. [3]

Butterflies are today distributed throughout the world except in the very cold and arid regions. There are an estimated 18,000 species of butterflies.


Presently butterflies are classified in two superfamilies, Hesperioidea, consisting of the 'skippers' and Papilionoidea or 'true butterflies'. These are sister taxa, so the butterflies collectively are thought to constitute a true clade. Some taxonomists place them all in superfamily Papilionoidea, distinguishing the skippers from the other butterflies at the series level only. In this system, Papilionoidea consists of the series Hesperiiformes (with one family only, the skipper family Hesperiidae) and the series Papilioniformes (with five families).

Butterfly families

The five families of true butterflies usually recognized in the Papilionoidea are:-

  • Family Papilionidae, the Swallowtails and Birdwings
  • Family Pieridae, the Whites and Yellows
  • Family Lycaenidae, the Blues and Coppers, also called the Gossamer-Winged Butterflies
  • Family Riodinidae, the Metalmark butterflies
  • Family Nymphalidae, the Brush-footed butterflies

Taxonomic issues

A study combining morphological and molecular data concluded that Hesperiidae, Papilionidae, Pieridae, Lycaenidae and Riodinidae could all be strongly supported as monophyletic groups, but the status of Nymphalidae is uncertain. Lycaenidae and Riodinidae were confirmed as sister taxa, and Papilionidae as the outgroup to the rest of the true butterflies, but the location of Pieridae within the pattern of descent was unclear, with different lines of evidence suggesting different conclusions. The data suggested that the moths of Hedyloidea are indeed more closely related to the butterflies than to other moths.[4]

Some older classifications recognize additional families, for example Danaidae, Heliconiidae, Libytheidae and Satyridae, but modern classifications treat these as subfamilies within the Nymphalidae.

Butterflies and moths

The dichotomous classfication of lepidopterans into butterflies and moths is one that is popular but not used in taxonomy. The folk groups of butterflies and moths can be distinguished using several features but there are exceptions to most of these rules. (See difference between a butterfly and a moth)

The four stages in the lifecycle of a butterfly

Mating Butterflies

Unlike many insects, butterflies do not experience a nymph period, but instead go through a pupal stage which lies between the larva and the adult stage (the imago). Butterflies are termed as holometabolous insects, and go through complete metamorphosis.

  • Egg
  • Larva, known as a caterpillar
  • Pupa (chrysalis)
  • Adult butterfly (imago)

It is a popular belief that butterflies have very short life spans. However butterflies in their adult stage can live from a week to nearly a year depending on the species. Many species have long larval life stages while others can remain dormant in their pupal and egg stages.[5]


Butterfly eggs consist of a hard-ridged outer layer of shell, called the chorion. This is lined with a thin coating of wax which prevents the egg from drying out before the larva has had time to fully develop. Each egg contains a number of tiny funnel-shaped openings at one end, called micropyles; the purpose of these holes is to allow sperm to enter and fertilize the egg. Butterfly and moth eggs vary greatly in size between species, but they are all either spherical or ovate.

Butterfly eggs are fixed to a leaf with a special glue which hardens rapidly. As it hardens it contracts deforming the shape of the egg. This glue is easily seen surrounding the base of every egg forming a meniscus. The nature of the glue is unknown, and is a suitable subject for research. The same glue is produced by a pupa to secure the setae of the cremaster. This glue is so hard that the silk pad, to which the setae are glued, cannot be separated.

Eggs are usually laid on plants. Each species of butterfly has its own hostplant range and while some species are restricted to just one species, others use a range of plant species, often members of a common family.


Larvae, or caterpillars, are multi-legged eating machines. They consume plant leaves and spend practically all of their time in search of food. Some larvae, especially those of the Lycaenidae form mutualistic associations with ants. They communicate with the ants using vibrations that are transmitted through the substrate as well as using chemical signals.[6][7] The ants provide some degree of protection to these larvae and they in turn gather honeydew secretions.

Although most caterpillars are herbivorous, a few species are carnivorous.

Caterpillars mature through a series of stages, called instars. Near the end of each instar, the larva undergoes a process called apolysis, in which the cuticle, a mixture of chitin and specialized proteins, is released from the epidermis and the epidermis begins to form a new cuticle beneath. At the end of each instar, the larva moults the old cuticle, and the new cuticle rapidly hardens and pigments. Development of butterfly wing patterns begins by the last larval instar.

Butterfly caterpillars have three pairs of true legs from the thoracic segments and upto 6 pairs of prolegs arising from the abdominal segments. These prolegs have rings of tiny hooks called crochets that help them grip the substrate.

Some caterpillars have the ability to inflate parts of their head to appear snake-like. Many have false eye-spots to enhance this effect. Some caterpillars have special structures called osmeteria which are everted to produce smelly chemicals. These are used in defense.

Host plants often have toxic substances in them and caterpillars are able to sequester these substances and retain them into the adult stage. This helps making them unpalatable to birds and other predators. Such unpalatibility is advertised using bright red, orange, black or white warning colours.

Wing development

Last instar wing disk, Junonia coenia
Last instar wing disk, Junonia coenia

Wings or wing pads are not visible on the outside of the larva, but when larvae are dissected, tiny developing wing disks can be found on the second and third thoracic segments, in place of the spiracles that are apparent on abdominal segments.

Wing disks develop in association with a trachea that runs along the base of the wing, and are surrounded by a thin peripodial membrane, which is linked to the outer epidermis of the larva by a tiny duct.

Wing disks are very small until the last larval instar, when they increase dramatically in size, are invaded by branching tracheae from the wing base that precede the formation of the wing veins, and begin to express molecular markers in patterns associated with several landmarks of the wing.

Near pupation, the wings are forced outside the epidermis under pressure from the hemolymph, and although they are initially quite flexible and fragile, by the time the pupa breaks free of the larval cuticle they have adhered tightly to the outer cuticle of the pupa (in obtect pupae). Within hours, the wings form a cuticle so hard and well-joined to the body that pupae can be picked up and handled without damage to the wings.


When the larva is fully grown, hormones such as prothoracicotropic hormone (PTTH) are produced. At this point the larva stops feeding and begins "wandering" in the quest of a suitable pupation site, often the underside of a leaf.

The larva transforms into a pupa (or chrysalis) by anchoring itself to a subtrate and moulting for the last time. The chrysalis is usually incapable of movement, although some species can rapidly move the abdominal segments or produce sounds to scare potential predators.

The pupal transformation into a butterfly through metamorphosis has held great appeal to mankind. To transform from the miniature wings visible on the outside of the pupa into large structures usable for flight, the pupal wings undergo rapid mitosis and absorb a great deal of nutrients. If one wing is surgically removed early on, the other three will grow to a larger size. In the pupa, the wing forms a structure that becomes compressed from top to bottom and pleated from proximal to distal ends as it grows, so that it can rapidly be unfolded to its full adult size. Several boundaries seen in the adult color pattern are marked by changes in the expression of particular transcription factors in the early pupa.

Adult or Imago

The adult, sexually mature, stage of the insect is known as the imago. As Lepidoptera, butterflies have four wings that are covered with tiny scales (see photo), but, unlike moths, the fore and hindwings are not hooked together, permitting a more graceful flight. A adult butterfly has six legs, but in the nymphalids, the first pair is reduced. After it emerges from its pupal stage, a butterfly cannot fly until the wings are unfolded. A newly-emerged butterfly needs to spend some time inflating its wings with blood and letting them dry, during which time it is extremely vulnerable to predators.

Many adult butterflies exhibit polymorphism, showing differences in appearance. These variations include geographic variants and seasonal forms. In addition many species have females in multiple forms, often with mimetic forms. Sexual dimorphism in colouration and appearance is widespread in butterflies. In addition many species show sexual dimorphism in the patterns of ultraviolet reflectivity, while otherwise appearing identical to the unaided human eye.

Genetic abnormalities such as gynandromorphs also occur from time to time.

Batesian mimicryBatesian and Mullerian mimicry in butterflies is common. Wing markings called eyespots are present in some species; these may have an automimicry role for some species. In others, the function may be intraspecies communication, such as mate attraction. In several cases, however, the function of butterfly eyespots is not clear, and may be an evolutionary anomaly related to the relative elasticity of the genes that encode the spots.[8][9]


Butterflies live primarily on nectar from flowers. Some also derive nourishment from pollen, tree sap, rotting fruit, dung, and dissolved minerals in wet sand or dirt. Butterflies play an important ecological role as pollinators.

As adults, butterflies are consume only liquids and these are sucked by means of their proboscis. They feed on nectar from flowers and also sip water from damp patches. This they do for water, for energy from sugars in nectar and for sodium and other minerals which are vital for their reproduction. Several species of butterflies need more sodium than provided by nectar. They are attracted to sodium in salt and they sometimes land on people, attracted by human sweat. Besides damp patches, some butterflies also visit dung, rotting fruit or carcasses to obtain minerals and nutrients. In many species, this behaviour is restricted to the males and studies have suggested that the nutrients collected are provided as a nuptial gift along with the spermatophore during mating. [10]

Butterflies sense the air for scents, wind and nectar using their antennae. The antennae come in various shapes and colours. The hesperids have a pointed angle or hook to the antennae, while most other families show knobbed antennae. The antennae are richly covered with sensillae. Chemoreceptors are also present on the tarsi and these work only on contact. Butterflies often use chemical signals, pheromones, and specialized scales and other structures are developed in some species.

Vision is well developed in butterflies and most species are sensitive to the ultraviolet spectrum. Many species show sexual dimorphism in the patterns of UV reflective patches.[11] Colour vision may be widespread but has been demonstrated in only a few species.[12][13]

Some butterflies have organs of hearing and some species are also known to make stridulatory and clicking sounds.[14]

Many butterflies, such as the Monarch butterfly, are migratory and capable of long distance flights. They migrate during the day and use the sun to orient themselves. They also perceive polarized light and use it for orientation when the sun is hidden.[15]

Many species of butterfly maintain territories and actively chase other species or individuals that may stray into them. Some species will bask or perch on chosen perches. The flight styles of butterflies are often characteristic and some species have courtship flight displays. Basking is an activity which is commoner in the cooler hours of the morning. Many species will orient themselves to gather heat from the sun. Some species have evolved dark wingbases to help in gathering more heat and this is especially evident in alpine forms.[16]


Unlike many other members of the insect world, the flight of a butterfly can be explained quantitatively (and quite accurately) using steady-state, non-transitory aerodynamics. The aspect ratio of a butterfly's wing is ideal to be described using thin airfoil theory. The fluttering of the wings merely serves to enforce the Kutta condition of low-speed aerodynamics. For a more detailed description, see Insect flight.


Butterflies have many predators and they have evolved a variety of defenses.

Chemical defenses are widespread and are often based on chemicals of plant origin. In many cases the plants themselves have evolved these toxic substances to reduce attack to them. These defense mechanisms are effective only if they are also well advertised. Many unpalatable butterflies are brightly coloured. This has also led to the evolution of mimetic forms in other butterflies which may not be as well protected.

Cryptic colouration is found in many butterflies. Some like the oakleaf butterfly are remarkable imitations of leaves.[17] As caterpillars many defend themselves by freezing and appearing like sticks or branches. Some papilionid caterpillars resemble bird dropping in their early instars.

Behavioural defenses include perching and wing positions to avoid being conspicuous. Some female Nymphalid butterflies are known to guard their eggs from parasitoid wasps.[18]

Eyespots and tails are found in many lycaenid butterflies and these divert the attention of predators from the more vital head region. An alternative theory is that these cause ambush predators such as spiders to approach from the wrong end and allow for early visual detection.[19]

Study of butterflies

Scientists who study butterflies (or the closely related moths) are called lepidopterists and in former times were also known as aurelians. In earlier times, the study of butterflies invariably involved their capture and collection. The butterfly net and cabinet mark the Victorian era of natural history studies.

The tools of butterfly research have changed over time. Molecular tools have become prominent in the study of butterflies. The basis for classification has gradually moved from morphological features to those based on DNA sequences.

Field guides for various regions have made butterfly-watching and field studies popular. Collaborative studies have produced distribution maps, seasonal patterns and behavioural notes on a number of butterfly species. Most butterflies can be identified in the field based on their patterns, however some are notoriously difficult or impossible. In some groups, the species identity can be established only through dissection and examination of the genitalia.

Cultural Views

China and Japan

According to the “Butterflies” chapter in Kwaidan: Stories and Studies of Strange Things, by Lafcadio Hearn, a butterfly is seen as the personification of a person's soul, whether they be living, dying, or already dead. One Japanese superstition says that if a butterfly enters your guestroom and perches behind the bamboo screen, the person whom you most love is coming to see you. On the contrary, large numbers of butterflies are viewed as bad omens. When Taira no Masakado was secretly preparing for his famous revolt, there appeared in Kyoto so vast a swarm of butterflies that the people were frightened—-thinking the apparition to be a portent of coming evil. [20]
