Adalbert Seitz
Friedrich Joseph Adalbert Seitz, (24 February 1860 in Mainz – 5 March 1938 in Darmstadt) was a German physician and entomologist who specialised in Lepidoptera. He was a director of the Frankfurt zoo from 1893 to 1908 and is best known for editing the multivolume reference on the butterflies and larger moths of the world ''Die Gross-Schmetterlinge der Erde'' which continued after his death. Biography Seitz was born in Mainz and went to school in Aschaffenburg, Darmstadt and Bensheim. He studied medicine from 1880 to 1885 and then zoology at Giessen. His doctorate was on the protective devices of animals. He worked as an assistant in the maternity hospital of the University of Giessen and then worked as a ship's doctor from 1887, travelling to Australia, South America and Asia. He began to collect butterflies on these travels. In 1891 he habilitated in zoology with a thesis on the biology of butterflies from the University of Giessen.

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterfly
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the Order (biology), order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily (zoology), superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo Holometabolism, complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nymphalidae
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, they 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.

South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively.

Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically extent, is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is distance between the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90º angle. Former professional basketball player Manute Bol stood at and owned one of the largest wingspans at . Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, independently of wing shape or sweep. Implications for aircraft design and anima ...

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Ehrharta Erecta
''Ehrharta erecta'' is a species of grass commonly known as panic veldtgrass. The species is native to Southern Africa and Yemen. It is a documented invasive species in the United States, New Zealand, Australia, southern Europe, and China. The species is perennial, and normally grows to about 30 to 50 centimeters, although it may reach two meters in height. It will grow in a wide variety of habitats, even in shade. The species has been used for birdseed, and in ecological restoration such as dune stabilization. However, it has become an invasive weed in many parts of the world. Flowering and seeding throughout the year, its seeds germinate rapidly, forming new plants in only a few weeks. Distribution It was first recorded in Ireland in 2017, but there are earlier records from Great Britain Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest Europ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennisetum Clandestinum
The tropical grass species ''Cenchrus clandestinus'' (previously Pennisetum clandestinum) is known by several common names, most often kikuyu grass, as it is native to the highland regions of East Africa that is home to the Kikuyu people. Because of its rapid growth and aggressive nature, it is categorised as a noxious weed in some regions. However, it is also a popular garden lawn species in Australia, New Zealand, South Africa and the southern region of California in the United States, as it is inexpensive and moderately drought-tolerant. In addition, it is useful as pasture for livestock grazing and serves as a food source for many avian species, including the long-tailed widowbird. The flowering culms are very short and "hidden" amongst the leaves, giving this species its specific epithet (''clandestinus''). Description and habitat ''Cenchrus clandestinus'' is a rhizomatous grass with matted roots and a grass-like or herbaceous habit. The leaves are green, flattened or ...

Stipa Dregeana
''Stipa'' is a genus of around 300 large perennial hermaphroditic grasses collectively known as feather grass, needle grass, and spear grass. They are placed in the subfamily Pooideae and the tribe Stipeae, which also contains many species formerly assigned to ''Stipa'', which have since been reclassified into new genera. Many species are important forage crops. Several species such as ''Stipa brachytricha'', ''S. arundinacea'', ''S. splendens'', ''S. calamagrostis'', ''S. gigantea'' and ''S. pulchra'' are used as ornamental plants. One former species, esparto grass (''Macrochloa tenacissima''), is used for crafts and extensively in paper making. It is a coarse grass with inrolled leaves and a panicle patterned inflorescence. Ecology Species of the genus ''Stipa'' can occur in grasslands or in savanna habitats. Certain specific prairie plant associations are dominated by grasses of the genus ''Stipa'', which genus often lends its name to the terminology of some prairie types. ...

Panicum Deustrum
''Panicum'' (panicgrass) is a large genus of about 450 species of grasses native throughout the tropical regions of the world, with a few species extending into the northern temperate zone. They are often large, annual or perennial grasses, growing to tall. The flowers are produced in a well-developed panicle often up to in length with numerous seeds, which are long and broad. The fruits are developed from a two-flowered spikelet. Only the upper floret of each spikelet is fertile; the lower floret is sterile or staminate. Both glumes are present and well developed. Australia has 29 native and 9 introduced species of ''Panicum''. Well-known ''Panicum'' species include ''Panicum miliaceum'' (proso millet) and ''Panicum virgatum'' (switchgrass).
