Melanargia Galathea
''Melanargia galathea'', the marbled white, is a medium-sized butterfly in the family Nymphalidae. Despite its common name and appearance, this butterfly is one of the "browns", of the subfamily Satyrinae. This species can be found across most of Europe, southern Russia, Asia Minor and Iran. It is found in forest clearings and edges, meadows and steppe where it occurs up to above sea level. The caterpillars feed on various grasses. Subspecies Subspecies include:"''Melanargia'' Meigen, 1828" at Markku Savela's ''Lepidoptera and Some Other Life Forms'' *''Melanargia galathea galathea'' Europe, southern Urals *''Melanargia galathea donsa'' Fruhstorfer, 1916 Caucasus *''Melanargia galathea lucasi'' (Rambur, 1858) North Africa * ...

Oxfordshire
Oxfordshire is a ceremonial and non-metropolitan county in the north west of South East England. It is a mainly rural county, with its largest settlement being the city of Oxford. The county is a centre of research and development, primarily due to the work of the University of Oxford and several notable science parks. These include the Harwell Science and Innovation Campus and Milton Park, both situated around the towns of Didcot and Abingdon-on-Thames. It is a landlocked county, bordered by six counties: Berkshire to the south, Buckinghamshire to the east, Wiltshire to the south west, Gloucestershire to the west, Warwickshire to the north west, and Northamptonshire to the north east. Oxfordshire is locally governed by Oxfordshire County Council, together with local councils of its five non-metropolitan districts: City of Oxford, Cherwell, South Oxfordshire, Vale of White Horse, and West Oxfordshire. Present-day Oxfordshire spanning the area south of the Thames was h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bromus Erectus
''Bromus erectus'', commonly known as erect brome, upright brome or meadow brome, is a dense, course, tufted perennial grass. It can grow to . Like many brome grasses the plant is hairy. The specific epithet ''erectus'' is Latin, meaning "erect". The diploid number of the grass is 56. Description ''Bromus erectus'' is a perennial, tufted grass with basal tufts of cespitose leaves that is nonrhizomatous. The culms grow between in height. The internodes are typically glabrous. The flattened cauline leaves have pubescent or glabrous sheaths. The leaf blades are long and wide. The grass lacks auricles and the ligule is blunt but finely serrated, sometimes with hairy edges. The contracted and ellipsoid panicle is usually upright, rather than nodding, measuring long. The lanceolate spikelets are long and have five to twelve flowers. The glume In botany, a glume is a bract (leaf-like structure) below a spikelet in the inflorescence (flower cluster) of grasses (Poaceae) or ...

Butterflies Of Europe
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 (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 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 out, and after its wings have expanded and dried, it fli ...

Melanargia
''Melanargia'' is a genus of butterflies belonging to the family Nymphalidae and the subfamily Satyrinae (formerly family Satyridae). This genus, described by Johann Wilhelm Meigen in 1828, is the only genus in the subtribe Melanargiina, Wheeler, 1903. The adults of this genus of satyrines are easily distinguished by their white wings with black veins and markings (hence the common name "marbled whites"). A peculiar phenotypic distinctiveness is also a dilated vein 12 at the base of the forewing. Butterflies of genus ''Melanargia'' are widespread from Europe and north Africa to Japan. Species and subspecies The investigations on genetic divergence and phylogenetic relationships among ''Melanargia'' species have recognized three subgenera (''Melanargia'', ''Argeformia'', and ''Halimede'') and reclassified the genus in 20 species and relevant subspecies as follows Subgenus ''Melanargia'' Meigen, 1829 * ''Melanargia galathea'' (Linnaeus, 1758) - marbled white ** ''Melanargia ga ...

Moses Harris
Moses Harris (15 April 1730 – 1787) was an English entomologist and engraver. Life and work Harris was encouraged in entomology from a young age by his uncle, a member of the Society of the Aurelians. In 1762 he became secretary of a second Society of Aurelians. He was a skilled artist, displaying some of his insect drawings at the Royal Academy in 1785. He drew and engraved illustrations for books including Dru Drury's ''Illustrations of Natural History'' (3 volumes, 1770–1782) and John Coakley Lettsom's ''The Naturalist's and Traveller's Companion'' (1772). Colour theory In "The Natural System of Colours" published in 1766, Harris discussed the multitude of colours that can be created using three "grand or principle" colours: red, yellow and blue. As a naturalist and an engraver, Harris focussed on the relationships between colours and how they are coded and created. He explained how three colours can be íntermixed, tinted and shaded to create 660 colours "materially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benjamin Wilkes
Benjamin Wilkes (died c. 1749) was an 18th-century artist and naturalist in London. Wilkes' profession was 'painting of History Pieces and Portraits in Oyl'. When a friend invited him to a meeting of the Aurelian Society, where he first saw specimens of butterflies and moths, he became convinced that nature would be his 'best instructor' as to colour and form in art. He began to study entomology spending his leisure time collecting, studying and drawing the adults, larvae, pupae and parasitoids (Tachinidae and Ichneumonidae) of Lepidoptera, assisted by the collector Mr. Joseph Dandridge. Wilkes' own collection was kept, "against the Horn Tavern in Fleet Street," London, "Where any gentleman or lady," could see his collection of insects. Henry Baker, writing in August 1749, stated that Wilkes had, "died of a fever in about a week after he had finished his laborious and elegant work," and paid tribute to Wilkes as, "indefatigable in his observations and faithful in minuting down eve ...

James Petiver
James Petiver (c. 1665 – c. 2 April 1718) was a London apothecary, a fellow of the Royal Society as well as London's informal Temple Coffee House Botany Club, famous for his specimen collections in which he traded and study of botany and entomology. He corresponded with John Ray and Maria Sibylla Merian. Some of his notes and specimens were used by Carolus Linnaeus in descriptions of new species. The genus ''Petiveria'' was named in his honour by Charles Plumier. His collections were bought by Sir Hans Sloane and became a part of the Natural History Museum. Life Born somewhere between 1663 and 1665 in Hillmorton, Warwickshire to James (baptism record from Hillmorton has "Pettyfer", 22 February 1635) and Mary née Elborow, the family moved to London soon after where his father became a haberdasher. After the death of his father in 1676, Petiver was sent to Rugby Free School, sponsored by his maternal grandfather Richard Elborow. Petiver later stated that "I have often bewailed m ...

Triticum
Wheat is a grass widely cultivated for its seed, a cereal grain that is a worldwide staple food. The many species of wheat together make up the genus ''Triticum'' ; the most widely grown is common wheat (''T. aestivum''). The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BCE. Botanically, the wheat kernel is a type of fruit called a caryopsis. Wheat is grown on more land area than any other food crop (, 2014). World trade in wheat is greater than for all other crops combined. In 2020, world production of wheat was , making it the second most-produced cereal after maize. Since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of the 21st century. Global demand for wheat is increasing due to the unique viscoelastic and adhesive properties of gluten proteins, which facilitate the production of processed foods, whose consumption is increas ...
