Xylota Segnis
''Xylota segnis'', The Brown-toed Forest Fly, is a common species of hoverfly. Etymology The genus name ''Xylota'' is the Latinized form of the rare Byzantine-Greek ξυλωτή sylōtēmeaning ''wooden'', while the Latin species name ''segnis'' means ''slipping'' or ''lazy'', as this hoverfly usually rests on a leaf and it does not fly frequently. The translation of the taxon could be "lazy wood fly". Distribution This species has a Palearctic and Nearctic distribution. It is present in all Europe including the Mediterranean, the Caucasus and through Russia to the Russian Far East and Japan. It is also present in the Nearctic eastern parts, in southeastern Canada and northeastern United States.GBIF species page, with map Habitat This species mainly inhabits low bushes in woods. Description Biology This species is polyvoltin, with up to three generations per year. Flight times last from April to September. Adults feed by grazing on anemophilous pollen grazed from surface ...

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 coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology Of Diptera
Dipteran morphology differs in some significant ways from the broader morphology of insects. The Diptera is a very large and diverse order of mostly small to medium-sized insects. They have prominent compound eyes on a mobile head, and (at most) one pair of functional, membraneous wings, which are attached to a complex mesothorax. The second pair of wings, on the metathorax, are reduced to halteres. The order's fundamental peculiarity is its remarkable specialization in terms of wing shape and the morpho-anatomical adaptation of the thorax – features which lend particular agility to its flying forms. The filiform, stylate or aristate antennae correlate with the Nematocera, Brachycera and Cyclorrhapha taxa respectively. It displays substantial morphological uniformity in lower taxa, especially at the level of genus or species. The configuration of integumental bristles is of fundamental importance in their taxonomy, as is wing venation. It displays a complete metamorphosis (egg, ...

Heracleum Sphondylium
''Heracleum sphondylium'', commonly known as hogweed, common hogweed or cow parsnip, is a herbaceous perennial or biennial plant, in the umbelliferous family Apiaceae that includes fennel, cow parsley, ground elder and giant hogweed. It is native to Europe and Asia. The common name eltrot may also be applied, but is not specific to this species. Umbelliferous plants are so named because of the umbrella-like arrangement of flowers they produce. The North American species '' Heracleum maximum'' (also called "cow parsnip") is sometimes included as a subspecies of ''H. sphondylium''. The plant provides a great deal of nectar for pollinators. It was rated in the top 10 for most nectar production (nectar per unit cover per year) in a UK plants survey conducted by the AgriLand project which is supported by the UK Insect Pollinators Initiative. Etymology The species name ''sphondylium'', meaning "vertebrate", refers to the shape of the segmented stem. It was described by Carl Linnaeu ...

Angelica Sylvestris
''Angelica sylvestris'' or wild angelica is a species of flowering plant, native to Europe and central Asia. An annual or short-lived perennial growing to a maximum of , it has erect purplish stems and rounded umbels of minuscule white or pale pink flowers in late summer. Habitat and ecology The Latin specific epithet ''sylvestris'' means “growing in woodland”. However it tolerates a range of conditions including fields, hedgerows, open woods, marshes and fens. It will grow in light (sandy), medium (loamy) and heavy (clay) soils. It has recently been determined to be an invasive weed in New Brunswick and Cape Breton, Nova Scotia, Canada. "According to the New Brunswick Invasive Species Council, unless this species is controlled, Woodland Angelica could spread throughout Canada, overwhelming other vegetation." The flowers are visited by a wide array of insects and are thus characterised by a generalised pollination system. Adult wasps of '' Dolichovespula norwegica'' are kno ...

Aegopodium Podagraria
''Aegopodium podagraria'', commonly called ground elder, is a species of flowering plant in the carrot family Apiaceae that grows in shady places. The name "ground elder" comes from the superficial similarity of its leaves and flowers to those of elder (''Sambucus''), which is not closely related. Other common names include herb gerard, bishop's weed, goutweed, gout wort, snow-in-the-mountain, English masterwort and wild masterwort. It is the type species of the genus ''Aegopodium''. It is native to Europe and Asia, but has been introduced around the world as an ornamental plant, where it occasionally poses an ecological threat as an invasive exotic plant. Description This herbaceous perennial grows to a height of from underground rhizomes. The stems are erect, hollow, and grooved. The upper leaves are ternate, broad and toothed.

Rubus Idaeus
''Rubus idaeus'' (raspberry, also called red raspberry or occasionally European red raspberry to distinguish it from other raspberry species) is a red-fruited species of ''Rubus'' native to Europe and northern Asia and commonly cultivated in other temperate regions. Taxonomy A closely related plant in North America, sometimes regarded as the variety ''Rubus idaeus'' var. ''strigosus'', is more commonly treated as a distinct species, '' Rubus strigosus'' (American red raspberry), as is done here. Red-fruited cultivated raspberries, even in North America, are generally ''Rubus idaeus'' or horticultural derivatives of hybrids of ''R. idaeus'' and ''R. strigosus;'' these plants are all addressed in the present article. Description Plants of ''Rubus idaeus'' are generally perennials, which bear biennial stems ("canes") from a perennial root system. In its first year, a new, unbranched stem (" primocane") grows vigorously to its full height of 1.5–2.5 m (5.0–8.3 feet), bearing la ...

Corylus Avellana
''Corylus avellana'', the common hazel, is a species of flowering plant in the birch family Betulaceae. It is native to Europe and western Asia. It is an important component of the hedgerows that were the traditional field boundaries in lowland England. The wood was traditionally grown as coppice, the poles cut being used for wattle-and-daub building and agricultural fencing. Common hazel is cultivated for its nuts. The name hazelnut applies to the nuts of any species in the genus ''Corylus'', but in commercial settings a hazelnut is usually that of ''C. avellana''. This hazelnut or cob nut, the kernel of the seed, is edible and used raw or roasted, or ground into a paste. The cob is round, compared with the longer filbert nut. Description Common hazel is typically a shrub reaching tall, but can reach . The leaves are deciduous, rounded, long and across, softly hairy on both surfaces, and with a double-serrate margin. The flowers are produced very early in spring, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voltinism
Voltinism is a term used in biology to indicate the number of broods or generations of an organism in a year. The term is most often applied to insects, and is particularly in use in sericulture, where silkworm varieties vary in their voltinism. * Univoltine (monovoltine) – (adjective) referring to organisms having one brood or generation per year * Bivoltine (divoltine) – (adjective) referring to organisms having two broods or generations per year *Trivoltine – (adjective) referring to organisms having three broods or generations per year * Multivoltine (polyvoltine) – (adjective) referring to organisms having more than two broods or generations per year * Semivoltine – There are two meanings: :* (''biology'') Less than univoltine; having a brood or generation less often than once per year :* or (adjective) referring to organisms whose generation time is more than one year. Examples The speckled wood butterfly is univoltine in the northern part of its range, e.g. nort ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
