In chaos theory, the butterfly effect is the sensitive dependence on initial conditions in which a small change in one state of a deterministic nonlinear system can result in large differences in a later state.
Madama Butterfly is an opera in three acts by Giacomo Puccini, with an Italian libretto by Luigi Illica and Giuseppe Giacosa.
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers, and the most recent analyses suggest it also contains the moth-butterflies. Butterfly fossils date to the Paleocene, which was about 56 million years ago.
Lepidoptera is an order of insects that includes butterflies and moths. About 180,000 species of the Lepidoptera are described, in 126 families and 46 superfamilies, 10 per cent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most speciose orders, along with the Hymenoptera, Diptera, and Coleoptera.
Moths comprise a group of insects related to butterflies, belonging to the order Lepidoptera. Most lepidopterans are moths, and there are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species.
The monarch butterfly or simply monarch is a milkweed butterfly in the family Nymphalidae. Other common names depending on region include milkweed, common tiger, wanderer, and black veined brown. It may be the most familiar North American butterfly, and is considered an iconic pollinator species. Its wings feature an easily recognizable black, orange, and white pattern, with a wingspan of 8.9–10.2 cm(3 1⁄2–4 in) The viceroy butterfly is similar in color and pattern, but is markedly smaller and has an extra black stripe across each hindwing.
The Nymphalidae are the largest family of butterflies with more than 6,000 species distributed throughout most of the world, belonging to the superfamily Papilionoidea. These are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colourful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies, because they are known to stand on only four legs while the other two are curled up; in some species, these forelegs have a brush-like set of hairs, which gives this family its other common name. Many species are brightly coloured and include popular species such as the emperors, monarch butterfly, admirals, tortoiseshells, and fritillaries. However, the under wings are, in contrast, often dull and in some species look remarkably like dead leaves, or are much paler, producing a cryptic effect that helps the butterflies blend into their surroundings.
The Pieridae are a large family of butterflies with about 76 genera containing about 1,100 species, mostly from tropical Africa and tropical Asia with some varieties in the more northern regions of North America. Most pierid butterflies are white, yellow, or orange in coloration, often with black spots. The pigments that give the distinct coloring to these butterflies are derived from waste products in the body and are a characteristic of this family.
A pupa is the life stage of some insects undergoing transformation between immature and mature stages. The pupal stage is found only in holometabolous insects, those that undergo a complete metamorphosis, with four life stages: egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone.
Skippers are a family, the Hesperiidae, of the Lepidoptera. Being diurnal, they are generally called butterflies. They were previously placed in a separate superfamily, Hesperioidea; however, the most recent taxonomy places the family in the superfamily Papilionoidea. They are named for their quick, darting flight habits. Most have their antenna tips modified into narrow, hook-like projections. More than 3500 species of skippers are recognized, and they occur worldwide, but with the greatest diversity in the Neotropical regions of Central and South America.
The butterfly is a swimming stroke swum on the chest, with both arms moving symmetrically, accompanied by the butterfly kick. While other styles like the breaststroke, front crawl, or backstroke can be swum adequately by beginners, the butterfly is a more difficult stroke that requires good technique as well as strong muscles. It is the newest swimming style swum in competition, first swum in 1933 and originating out of the breaststroke.
The Butterfly Effect is a 2004 American science fiction thriller film written and directed by Eric Bress and J. Mackye Gruber, starring Ashton Kutcher and Amy Smart. The title refers to the butterfly effect, a popular hypothetical situation which illustrates how small initial differences may lead to large unforeseen consequences over time.
Swallowtail butterflies are large, colorful butterflies in the family Papilionidae, and include over 550 species. Though the majority are tropical, members of the family inhabit every continent except Antarctica. The family includes the largest butterflies in the world, the birdwing butterflies of the genus Ornithoptera.
The Satyrinae, the satyrines or satyrids, commonly known as the browns, are a subfamily of the Nymphalidae. They were formerly considered a distinct family, Satyridae. This group contains nearly half of the known diversity of brush-footed butterflies. The true number of the Satyrinae species is estimated to exceed 2400.
Polyommatinae, the blues, are a subfamily of gossamer-winged butterflies (Lycaenidae). It was long used to assign taxa of unclear relationships, and its contents are in need of revision. Several genera might not even belong here.
Michael Fred Phelps II is an American retired competitive swimmer and the most successful and most decorated Olympian of all time, with a total of 28 medals. Phelps also holds the all-time records for Olympic gold medals (23), Olympic gold medals in individual events (13), and Olympic medals in individual events (16). When he won eight gold medals at the 2008 Beijing Games, Phelps broke fellow American swimmer Mark Spitz's 1972 record of seven first-place finishes at any single Olympic Games. At the 2004 Summer Olympics in Athens, Phelps had already tied the record of eight medals of any color at a single Games by winning six gold and two bronze medals. At the 2012 Summer Olympics in London, Phelps won four gold and two silver medals, and at the 2016 Summer Olympics in Rio de Janeiro, he won five gold medals and one silver. This made him the most successful athlete of the Games for the fourth Olympics in a row.
The Butterfly Garden or Jardin des Papillons is located in Grevenmacher in eastern Luxembourg. Owned by the Caves Bernard-Massard wine company, the indoor site presents over 30 species of butterflies in natural surroundings made up of an impressive diversity of plants. The Butterfly Garden is open every day from 9.30 am to 5 pm from April to mid-October.
The HTC Butterfly is an Android-based, 4G LTE-capable smartphone designed and developed by HTC. First announced for release in Japan by Japanese carrier KDDI as the HTC J Butterfly (HTL21), the J Butterfly was released in Japan on 9 December 2012 as the successor to the HTC J. Outside Japan, in other Asian countries, the phone was released as the HTC Butterfly (X920d) and in China and Russia as the HTC Butterfly (X920e). The Chinese/Russian and US versions of the Butterfly do not have a microSD slot. In the United States, the Butterfly was released as the HTC Droid DNA as a Verizon exclusive, supporting wireless charging. The DNA would become Verizon's final non-Motorola Droid smartphone; following its replacement in August 2013 by the HTC One and Droid Maxx, the carrier announced that all future Droid phones would be built exclusively by Motorola. In June 2013, the Butterfly was succeeded by the HTC Butterfly S.
To Pimp a Butterfly is the third studio album by American rapper Kendrick Lamar. It was released on March 15, 2015, by Aftermath Entertainment, Interscope Records and Top Dawg Entertainment.
