True flies'" are insects of the Order "'Diptera'" (=two, and "pteron"= wing), possessing a single pair of wings on the mesothorax and a pair of halteres, derived from the hind wings, on the metathorax. The presence of a single pair of wings distinguishes true flies from other insects with "fly" in their name, such as mayflies, dragonflies, damselflies, stoneflies, whiteflies, fireflies, alderflies, dobsonflies, snakeflies, sawflies, caddisflies, butterflies or scorpionflies. Some true flies have become secondarily wingless, especially in the superfamily Hippoboscoidea, or among those that are inquilines in social insect colonies. Diptera is a large order, containing an estimated 240,000 species of mosquitos, gnats, midges and others, although under half of these (about 120,000 species) have been described. It is one of the major insect orders both in terms of ecological and human (medical and economic) importance. The Diptera, in particular the mosquitoes (Culicidae), are of great importance as disease transmitters, acting as vectors for malaria, dengue, West Nile virus, yellow fever, encephalitis and other infectious diseases. Classification. There are two generally accepted suborders of Diptera. The Nematocera are usually recognized by their elongated bodies and feathery antennae as represented by mosquitoes and crane flies. The Brachycera tend to have a more roundly proportioned body and very short antennae. A more recent classification has been proposed in which the Nematocera is split into two suborders, the Archidiptera and the Eudiptera, but this has not yet gained widespread acceptance among dipterists. Most of the Muscomorpha are further subdivided into the Acalyptratae and Calyptratae based on whether or not they have a calypter (a wing flap that extends over the halteres). Beyond that, considerable revision in the taxonomy of the flies has taken place since the introduction of modern cladistic techniques, and much remains uncertain. The secondary ranks between the suborders and the families are more out of practical or historical considerations than out of any strict respect for phylogenetic classifications (some modern cladists tend to spurn the use of Linnaean rank names). Nearly all classifications in use now, including this article, contain some paraphyletic groupings; this is emphasized where the numerous alternative systems are most greatly at odds. See list of families of Diptera. Dipterans belong to the group Mecopterida, that also contains Mecoptera, Siphonaptera, Lepidoptera (butterflies and moths) and Trichoptera. Inside it, they are sometimes classified closely together with Mecoptera and Siphonaptera in the superorder Antliophora. Evolution. Diptera are usually thought to derive from Mecoptera or a strictly related group. First true dipterans are known from the Middle Triassic, becoming widespread during the Middle and Late Triassic . Flies in culture. Flies have often been used in mythology and literature to represent agents of death and decay, such as the Biblical fourth plague of Egypt, or portrayed as nuisances (e.g., in Greek mythology, Myiagros was a god who chased away flies during the sacrifices to Zeus and Athena, and Zeus sent a fly to bite the horse Pegasus causing Bellerophon to fall back to Earth when he attempted to ride to Mount Olympus), though in a few cultures the connotation is not so negative (e.g., in the traditional Navajo religion, Big Fly is an important spirit being). Emily Dickinson's poem "I Heard a Fly Buzz When I Died" also makes reference to flies in the context of death. Not surprisingly, in art and entertainment, flies are also used primarily to introduce elements of horror or the simply mundane; an example of the former is the 1958 science fiction film "The Fly" (remade in 1986), in which a scientist accidentally exchanges parts of his body with those of a fly. Examples of the latter include trompe l'oeil paintings of the fifteenth century such as "Portrait of a Carthusian" by Petrus Christus, showing a fly sitting on a fake frame , a 2001 art project by Garnet Hertz in which a complete web server was implanted into a dead fly, and various musical works (such as Yoko Ono's album "Fly", U2's song "The Fly," Dave Matthews' song "The Fly" and Béla Bartók's "From the Diary of a Fly"). The ability of flies to cling to almost any surface has also inspired the title of "Human Fly" for stunt performers whose stunts involve climbing buildings, including both real life and fictional individuals. Aside from the fictional and conceptual role flies play in culture, there are practical roles that flies can play (e.g., flies are reared in large numbers in Japan to serve as pollinators of sunflowers in greenhouses), especially the maggots of various species. Maggots. Some types of maggots found on corpses can be of great use to forensic scientists. By their stage of development, these maggots can be used to give an indication of the time elapsed since death, as well as the place the organism died. Maggot species can be | 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. |
