A butterfly'" is an insect of the order Lepidoptera. Like all Lepidoptera, butterflies are notable for their unusual life cycle with a larval caterpillar stage, an inactive pupal stage, and a spectacular metamorphosis into a familiar and colourful winged adult form. Most species are day-flying so they regularly attract attention. The diverse patterns formed by their brightly coloured wings and their erratic yet graceful flight have made butterfly watching a hobby. Butterflies comprise the "true butterflies" (superfamily Papilionoidea), the "skippers" (superfamily Hesperioidea) and the "moth-butterflies" (superfamily Hedyloidea). Butterflies exhibit polymorphism, mimicry and aposematism. Some migrate 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. In addition, a few species are pests, because they can damage domestic crops and trees in their larval stage. Culturally, butterflies are a popular motif in the visual and literary arts. The four-stage lifecycle. 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. 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 or egg stages and thereby survive winters. Butterflies may have one or more broods per year. The number of generations per year varies from temperate to tropical regions with tropical regions showing a trend towards multivoltinism. Egg. 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 of butterfly are restricted to just one species of plant, others use a range of plant species, often including members of a common family. The egg stage lasts a few weeks in most butterflies but eggs laid close to winter, especially in temperate regions, go through a "diapause" stage, and the hatching may take place only in spring. Other butterflies may lay their eggs in the spring and have them hatch in the summer. These butterflies are usually northern species (Mourning Cloak, Tortoiseshells) Caterpillars. Butterfly larvae, or caterpillars, consume plant leaves and spend practically all of their time in search of food. Although most caterpillars are herbivorous, a few species such as "Spalgis epius" and "Liphyra brassolis" are entomophagous (insect eating). Some larvae, especially those of the Lycaenidae, form mutual associations with ants. They communicate with the ants using vibrations that are transmitted through the substrate as well as using chemical signals. The ants provide some degree of protection to these larvae and they in turn gather honeydew secretions. 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 up to 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 | A bottle'" is a container with a neck that is narrower than the body and a "mouth." Bottles are often made of glass, clay, plastic or other impervious materials, and typically used to store liquids such as water, milk, soft drinks, beer, wine, cooking oil, medicine, shampoo, ink and chemicals. A device applied in the bottling line to seal the mouth of a bottle is termed a bottle cap (external), or stopper (internal). A bottle can also be sealed using induction sealing. The bottle has developed over millennia of use, with some of the earliest examples appearing in China, Phoenicia, Rome and Crete. The Chinese used bottles to store liquids. In modern times for some bottles a legally mandated deposit is paid, which is refunded after returning the bottle to the retailer. For other glass bottles there is often separate garbage collection for recycling. History. Since prehistoric times, bottle containers were created from clay or asphaltum sealed woven containers. Early glass bottles were produced by the Phoenicians; specimens of Phoenician translucent and transparent glass bottles have been found in Cyprus and Rhodes generally varying in length from three to six inches. These Phoenician examples from the first millennium BC were thought to have been used for perfume. The Romans For wine. The glass bottle was an important development in the history of wine, because, when combined with a high-quality stopper such as a cork, it allowed long-term aging of wine. Glass has all the qualities required for long-term storage. It eventually gave rise to "château bottling", the practice where an estate's wine is put in bottle at the source, rather than by a merchant. Prior to this, wine would be sold by the barrel (and before that, the amphora) and put into bottles only at the merchant's shop, if at all. This left a large and often abused opportunity for fraud and adulteration, as the consumer had to trust the merchant as to the contents. It is thought that most wine consumed outside of wine-producing regions had been tampered with in some way. Also, not all merchants were careful to avoid oxidation or contamination while bottling, leading to large bottle variation. Particularly in the case of port, certain conscientious merchants' bottling of old ports fetch higher prices even today. To avoid these problems, most fine wine is bottled at the place of production (including all port, since 1974). There are many sizes and shapes of bottles used for wine. Some of the known shapes: Codd-neck bottles==. In 1872, British soft drink maker Hiram Codd of Camberwell, south east London, designed and patented a bottle designed specifically for carbonated drinks. The "'Codd-neck bottle'", as it was called, was designed and manufactured to enclose a marble and a rubber gasket in the neck. The bottles were filled upside down, and pressure of the gas in the bottle forced the marble against the washer, sealing in the carbonation. The bottle was pinched into a special shape, as can be seen in the photo to the right, to provide a chamber into which the marble was pushed to open the bottle. This prevented the marble from blocking the neck as the drink was poured Soon after its introduction, the bottle became extremely popular with the soft drink and brewing industries mainly in Europe, Asia and Australasia, though some alcohol drinkers disdained the use of the bottle. One etymology of the term "codswallop" originates from beer sold in Codd bottles. The bottles were regularly produced for many decades, but gradually declined in usage. Since children smashed the bottles to retrieve the marbles, they are relatively rare and have become collector items; particularly in the UK. A cobalt coloured Codd bottle today fetches thousands of British pounds at auction. The Codd-neck design is still used for the Japanese soft drink Ramune and in the Indian drink called Banta. Plastic bottles. Plastic bottles (e.g. two-liter) used for soft drinks can withstand typical internal carbonation pressures of 2–4 bar (30–60 psi.), because the plastic is strain oriented in the stretch blow molding manufacturing process. Aluminum bottles. The aluminum beverage bottle, launched in 2002, also known as a bottlecan, is made of recyclable aluminum with a resealable lug cap that fits onto a plastic sleeve. Some studies have concluded that aluminum provides for increased insulation keeping beverages cooler longer than glass. Capsules. Some jars and bottles have a metal cap or cover called a capsule. They were historically made of lead, and protected the cork from being gnawed away by rodents or infested with cork weevil. Because of research showing that trace amounts of lead could remain on the lip of the bottle, lead capsules (lead foil bottleneck wrappings) were slowly phased out, and by the 1990s most capsules were made of aluminum foil or plastic. |
