Metisella Meninx
''Metisella meninx'', the marsh sylph, is a butterfly of the family Hesperiidae. It is endemic to the wet vleis (shallow lakes) of highland grassland in northern KwaZulu-Natal, Mpumalanga, Gauteng, the northern part of the Free State and the extreme east of the North West Province. It has become extinct in many areas close to Johannesburg due to building developments. The wingspan is 26–28 mm for males and 27–29 mm for females. Adults are on wing from December to March (with a peak from January to February). There is one extended generation per year. Both sexes feed from flowers, those recorded including ''Scabiosa columbaria'', ''Persicaria attenuata'', ''Veronica anagallis-aquatica'' and ''Conyza podocephala''. Males occasionally drink from damp spots with decaying vegetation. The larvae feed on Poaceae marsh grass species, including ''Leersia hexandra ''Leersia hexandra'' is a species of grass known by the common names southern cutgrass, clubhead cutgra ...

Roland Trimen
Roland Trimen Fellow of the Royal Society, FRS (29 October 1840 in London – 25 July 1916 in London) was a British-South African Natural history, naturalist, best known for ''South African Butterflies'' (1887–89), a collaborative work with Colonel James Henry Bowker. He was among the first entomologists to investigate mimicry and Polymorphism (biology), polymorphism in butterflies and their restriction to females. He also collaborated with Charles Darwin to study the pollination of ''Disa (plant), Disa'' orchids. Life and career Trimen was born in London in 1840, the son of Richard and Mary Ann Esther Trimen and the older brother of the botanist Henry Trimen (1843-1896) who went to Ceylon (now Sri Lanka). He went to study at Rottingdean and then at King's College School in Wimbledon. Trimen was interested in entomology but a chronic Larynx, laryngeal condition forced him to move to the Cape of Good Hope as a treatment. Reaching there he volunteered under Edgar Leopold ...

Scabiosa Columbaria
''Scabiosa columbaria'', called the small scabious or dwarf pincushion flower, is a widespread species of flowering plant in the genus ''Scabiosa'', native to Europe, Africa, and western Asia, from Sweden to Angola. In the garden it is a short-lived deciduous perennial plant, perennial. In the wild in Europe it prefers to grow in calcareous grasslands. Growing to tall by , it has simple branched grey-green leaves, and pale lavender or blue multi-petalled flowers from summer to autumn. Subspecies The following subspecies are currently accepted: *''Scabiosa columbaria'' subsp. ''banatica'' (Waldst. & Kit.) Diklic *''Scabiosa columbaria'' subsp.

Butterflies Described In 1873
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] |

It has a distribution. It is also an in many regions, sometimes becoming invasive, and it is an agricultural weed of various crops, especially |
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, ...

Conyza Podocephala
''Conyza'' (horseweed, butterweed or fleabane) is a genus of flowering plants in the family Asteraceae. They are native to tropical and warm temperate regions throughout the world, and also north into cool temperate regions in North America and eastern Asia. The New World species of the genus are closely related to ''Erigeron'' (also known as fleabanes). The species are annual or perennial herbaceous plants, rarely shrubs, growing to 1–2 m tall. The stems are erect, branched, with alternate leaves. The flowers are produced in inflorescences, with several inflorescences loosely clustered on each stem. Many species of the genus ''Conyza'' are ruderal species and some have been found to be resistant to the herbicide glyphosate Glyphosate (IUPAC name: ''N''-(phosphonomethyl)glycine) is a broad-spectrum systemic herbicide and crop desiccant. It is an organophosphorus compound, specifically a phosphonate, which acts by inhibiting the plant enzyme 5-enolpyruvylshik ... ...

Veronica Anagallis-aquatica
''Veronica anagallis-aquatica'' is a species of flowering plant in the family Plantaginaceae known by the common names water speedwell, blue water-speedwell,brook pimpernel, and sessile water-speedwell. It is also listed as ''Veronica catenata''. Its true native range is not clear, but the plant is present on most continents, and in most places it is probably naturalized. It occurs in many types of moist and wet habitat, and it is semi-aquatic, often growing in shallow water along streambanks, in ponds, and in other wetland environments. It is a rhizomatous perennial herb with stems growing 10 centimeters to about a meter in maximum length. It may be decumbent, the stem spreading along the ground and rooting where it touches moist substrate, or erect in form. The oppositely arranged leaves are green, smooth-edged or toothed, and sometimes clasping the stem where the leaf pairs meet at the bases. The inflorescence is a raceme of many flowers arising from the leaf axils. Each flow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...
