Grey Chi
The grey chi (; ''Antitype chi'') is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in his 1758 10th edition of ''Systema Naturae''. It is distributed throughout Europe, although it is not present in southern Spain and Greece, as well as northern Fennoscandia. It is also found across the Palearctic including Central Asia, to the Russian Far East but not in Japan. This species has grey forewings speckled with black markings which vary in intensity (with the female generally more heavily marked than the male). There is usually a bold cross-shaped black mark in the centre of the wing which has been likened to the Greek letter chi (Χ) and gives the species its common name. The hindwings are white in the male, dirty grey in the female. Technical description and variation ''A. chi'' L. (33 i, 34 a). Forewing chalk white, grey-speckled; the lines double, grey; median area darker, the stigmata pale grey and conspicuous; the claviform at extrem ...

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] |
William Warren (entomologist)
William Warren (20 January 1839, in Cambridge – 18 October 1914, in Hemel Hempstead) was an English entomologist who specialised in Lepidoptera. William Warren was first educated at Oakham School, and subsequently graduated from the University of Cambridge, taking first-class classical honours in 1861. He then taught at Sedbergh School, Doncaster Grammar School (1866-1876) and Stubbington House School. He collected extensively in the British Isles, notably at Wicken Fen, with a special interest in Micro-lepidoptera. After giving up teaching in 1882, he lived in Cambridge and devoted himself fully to entomology, publishing around 40 papers on British moths between 1878 and 1889. Notably, in 1887 he was the first to recognise Grapholita pallifrontana (Lienig & Zeller) (Lep: Tortricidae) as a British species of micro-moth, a species which now has the English name the Liquorice Piercer and is of conservation concern. Later in the same year he successfully bred the moth and described ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackcurrant
The blackcurrant (''Ribes nigrum''), also known as black currant or cassis, is a deciduous shrub in the family Grossulariaceae grown for its edible berries. It is native to temperate parts of central and northern Europe and northern Asia, where it prefers damp fertile soils. It is widely cultivated both commercially and domestically. It is winter hardy, but cold weather at flowering time during the spring may reduce the size of the crop. Bunches of small, glossy black fruit develop along the stems in the summer and can be harvested by hand or by machine. Breeding is common in Scotland, Poland, Lithuania, Latvia, Norway, and New Zealand to produce fruit with better eating qualities and bushes with greater hardiness and disease resistance. The raw fruit is particularly rich in vitamin C and polyphenols. Blackcurrants can be eaten raw but are usually cooked in sweet or savoury dishes. They are used to make jams, preserves, and syrups and are grown commercially for the juice mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lychnis
''Silene'' is a genus of flowering plants in the family Caryophyllaceae. Containing nearly 900 species, it is the largest genus in the family. Common names include campion and catchfly. Many ''Silene'' species are widely distributed, particularly in the northern hemisphere. Scientific history Members of this genus have been the subject of research by preeminent plant ecologists, evolutionary biologists, and geneticists, including Charles Darwin, Gregor Mendel, Carl Correns, Herbert G. Baker, and Janis Antonovics. Many ''Silene'' species continue to be widely used to study systems, particularly in the fields of ecology and evolutionary biology.Bernasconi et al. 2009. Silene as a model system in ecology and evolution. Heredity. 103:5-14. PMI19367316/ref> The genus has been used as a model for understanding the genetics of sex determination for over a century.

Meadow Vetchling
''Lathyrus pratensis'' or meadow vetchling, yellow pea, meadow pea and meadow pea-vine, is a perennial legume that grows to 1.2 m in height. The hermaphrodite flowers are pollinated by bees. As a perennial, this plant reproduces itself over many years, spreading out from the point it was introduced, especially in damp grassy areas. This plant has been propagated in the past as animal fodder. ''Lathyrus pratensis'' is also a host plant for ovipositioning of the wood white butterfly (''Leptidea sinapis''). Description Meadow vetchling is a perennial plant with a limp, unwinged stem that grows to and is erect and hairy. The leaves are alternate with short stalks and large stipules. The leaf blades are pinnate with a single pair of broad lanceolate leaflets with blunt tips, entire margins and a terminal unbranched tendril.

Lettuce
Lettuce (''Lactuca sativa'') is an annual plant of the family Asteraceae. It is most often grown as a leaf vegetable, but sometimes for its stem and seeds. Lettuce is most often used for salads, although it is also seen in other kinds of food, such as soups, sandwiches and wraps; it can also be grilled. One variety, celtuce (asparagus lettuce), is grown for its stems, which are eaten either raw or cooked. In addition to its main use as a leafy green, it has also gathered religious and medicinal significance over centuries of human consumption. Europe and North America originally dominated the market for lettuce, but by the late 20th century the consumption of lettuce had spread throughout the world. , world production of lettuce and chicory was 27 million tonnes, 56percent of which came from China. Lettuce was originally farmed by the ancient Egyptians, who transformed it from a plant whose seeds were used to obtain oil into an important food crop raised for its succulent leav ...

Convallaria
''Convallaria'' is a genus of flowering plants. It is usually described as a monotypic genus with the single species ''Convallaria majalis'' (lily-of-the-valley), but now some botanists distinguish up to three species, also including ''Convallaria keiskei'' and '' Convallaria montana''. The generic name means valley in Botanical Latin Botanical Latin is a technical language based on New Latin, used for descriptions of botanical taxa. Until 2012, International Code of Botanical Nomenclature mandated Botanical Latin to be used for the descriptions of most new taxa.

Mugwort
Mugwort is a common name for several species of aromatic flowering plants in the genus ''Artemisia.'' In Europe, mugwort most often refers to the species '' Artemisia vulgaris'', or common mugwort. In East Asia the species '' Artemisia argyi'' is often called "Chinese mugwort" in the context of traditional Chinese medicine, or () in Mandarin. ''Artemisia princeps'' is a mugwort known in Korea as () and in Japan as (). While other species are sometimes referred to by more specific common names, they may be called simply "mugwort" in many contexts. Etymology The Anglo-Saxon ''Nine Herbs Charm'' mentions . A folk etymology, based on coincidental sounds, derives ' from the word "mug"; more certainly, it has been used in flavoring drinks at least since the early Iron Age. * Other sources say ''mugwort'' is derived from the Old Norse (meaning "marsh") and Germanic languages, German ''wuertz'' (''wort'' in English, originally meaning "root"), which refers to its use since ancient ti ...

British Isles
The British Isles are a group of islands in the North Atlantic Ocean off the north-western coast of continental Europe, consisting of the islands of Great Britain, Ireland, the Isle of Man, the Inner and Outer Hebrides, the Northern Isles, and over six thousand smaller islands."British Isles", ''Encyclopædia Britannica''. They have a total area of and a combined population of almost 72 million, and include two sovereign states, the Republic of Ireland (which covers roughly five-sixths of Ireland), and the United Kingdom of Great Britain and Northern Ireland. The Channel Islands, off the north coast of France, are normally taken to be part of the British Isles, even though they do not form part of the archipelago. The oldest rocks are 2.7 billion years old and are found in Ireland, Wales and the northwest of Scotland. During the Silurian period, the north-western regions collided with the south-east, which had been part of a separate continental landmass. The ...

Egg (biology)
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , the o ...

Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...
