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] |
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 forage, 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 bi ...

Hemiptera Of Europe
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs.

Mymaridae
The Mymaridae, commonly known as fairyflies or fairy wasps, are a family of chalcidoid wasps found in temperate and tropical regions throughout the world. The family contains around 100 genera with 1400 species. Fairyflies are very tiny insects, like most chalcidoid wasps, mostly ranging from long. They include the world's smallest known insect, with a body length of only , and the smallest known flying insect, only long. They usually have nonmetallic black, brown, or yellow bodies. The antennae of the females are distinctively tipped by club-like segments, while male antennae are thread-like. Their wings are usually slender and possess long bristles, giving them a hairy or feathery appearance, although some species may have greatly reduced stubby wings or lack wings altogether. They can be distinguished from other chalcidoids by the H-shaped pattern of sutures on the front of their heads. Fairyflies are among the most common chalcidoids, but are rarely noticed by humans bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dryinidae
Dryinidae is a cosmopolitan family of solitary wasps. Its name comes from the Greek ''drys'' for oak: Pierre André Latreille, Latreille named the type genus ''Dryinus'' because the first species was collected in an oak plant in Spain. The larvae are parasitoids of the nymphs and adults of Auchenorrhyncha. Dryinidae comprises approximately 1900 described species, distributed in 17 subfamilies and 53 genera. Description The adult wasp can measure from 0.9 to 5.0 mm in length and in some cases can reach 13 mm. The body of the adult wasp has a 'waist' where it is constricted in the middle. The rear legs have spurs which may be used for grooming. The antennae have 10 segments. Many species have a marked sexual dimorphism, where males are totally different from the females in the size and shape of the body. Males have wings while females are often wingless and resemble worker ants. The ovipositor is retractable and not visible when retracted. Life history The female dryinid ...

Tetragnatha Extensa
''Tetragnatha extensa'' is a species of spider found across the Northern Hemisphere. It has an elongate body, up to long, and adopts a straight line posture when alarmed. It lives on low vegetation in damp areas, and feeds on flying insects which it catches in its web. Description ''T. extensa'' has an elongated, cream-coloured body. Males are smaller than females, at around body length, compared to for females. The four pairs of legs are very long, and are dark yellow. The carapace, which is around 1.8–2.6 mm long and 1.1–1.7 mm wide, is orange or dark yellow. The colouring of ''T. extensa'' is quite variable, ranging from creamy-yellow to green. On the underside, there is a thick black central band, with a silvery band on either side. ''T. extensa'' is distinguished from other members of the genus ''Tetragnatha'' by the minute curved tip of the male's conductor (part of the pedipalp), and the form of the female's spermatheca.

Dolomedes Fimbriatus
The raft spider, scientific name ''Dolomedes fimbriatus'', is a large semi-aquatic spider of the family Pisauridae found throughout north-western and central Europe. It is one of only two species of the genus ''Dolomedes'' found in Europe, the other being the slightly larger ''Dolomedes'' ''plantarius'' which is endangered in the UK. Habitat and description Raft spiders are semi-aquatic and adults inhabit freshwater wetlands, specifically wet heaths and acid swamps; although juveniles are predominantly found in terrestrial vegetation surrounding wetland areas. Adults are dark brown with a conspicuous white, cream or yellow stripe along both sides of their abdomen and thorax. Juveniles are similar in appearance but often have green translucent legs. As is common in other spiders, female raft spiders (body length: 9–22mm) are usually larger than males (body length (9-15mm). Dolomedes fimbriatus was described in chapter 5 of the book ''Svenska Spindlar'' by the Swedish arachno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasteatoda Tepidariorum
''Parasteatoda tepidariorum'', the common house spider or American house spider, is a spider species of the genus ''Parasteatoda'' with a cosmopolitan distribution. Common house spiders are synanthropic and live in and near human dwellings. Their prey mechanism is similar to that of the other cobweb spiders: the spider follows disturbances transmitted along the web to entangle and then paralyze its prey, which usually consists of household insects and other invertebrates (often considered as pests). Description Appearance Common house spiders are variable in color from tan to nearly black, frequently with patterns of differing shades on their body. Females are generally between long, and males are generally between long. They can be an inch (2.5 cm) or more across with legs outspread. ''P. tepidariorum'' is similar in body shape to widow spiders. Males have a less bulbous abdomen than females. Common house spiders' size and coloration allow the spiders to blend into the ...

Climate Of Europe
Europe is generally characterized by a temperate climate. Most of Western Europe has an Oceanic climate, in the Köppen climate classification, featuring cool to warm summers and cool winters with frequent overcast skies. Southern Europe has a distinctively Mediterranean climate, which features warm to hot, dry summers and cool to mild winters and frequent sunny skies. Central-eastern Europe is classified as having a humid continental climate, which features warm to hot summers and cold winters. Parts of the central European plains have a hybrid oceanic/continental climate. Four seasons occur in most of Europe away from the Mediterranean. The coastal lowlands of the Mediterranean Basin have more of a wet winter and dry summer season pattern, the winter season extends from October to February while the summer season is mainly noticeable in the dry months where precipitation can, in some years, become extremely scarce. A very small area in the continent features the desert climate, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
