Lygus Wagneri
''Lygus wagneri'' is a species of plant bug belonging to the family Miridae, subfamily Mirinae. Description ''Lygus wagneri'' can reach a length of . These bugs have a golden gray to olive brown coloration, with small reddish areas. Head shows longitudinal dark brown lines between the eyes. The antennae are greyish brown. Scutellum has a W-shaped dark drawing. This species is extremely similar to ''Lygus pratensis'', although on average it is slightly smaller, with a shorter membrane. The corium is less densely pubescent. Biology ''Lygus wagneri'' has two generations per year. It has an incomplete metamorphosis, the transition from newly hatched larvae to the sexually mature insects gradually goes through several stages. It is a polyphagous species, mainly feeding on nectar of ''Tanacetum vulgare'' and on juices of ''Asteraceae'', ''Urtica dioica'', ''Rumex obtusifolius'', ''Hieracium'' and ''Hypericum''.

Miridae
The Miridae are a large and diverse insect family at one time known by the taxonomic synonym Capsidae. Species in the family may be referred to as capsid bugs or "mirid bugs". Common names include plant bugs, leaf bugs, and grass bugs. It is the largest family of true bugs belonging to the suborder Heteroptera; it includes over 10,000 known species, and new ones are being described constantly. Most widely known mirids are species that are notorious agricultural pests that pierce plant tissues, feed on the sap, and sometimes transmit viral plant diseases. Some species however, are predatory. Description Miridae are small, terrestrial insects, usually oval-shaped or elongate and measuring less than in length. Many of them have a hunched look, because of the shape of the prothorax, which carries the head bent down. Some are brightly coloured and attractively patterned, others drab or dark, most being inconspicuous. Some genera are ant mimics at certain stages of life. The Mirida ...

Lygus Pratensis
''Lygus pratensis'' is a species of plant bug belonging to the family Miridae. Distribution and habitat This species can be found in most of Europe, in Africa, in Northern Asia (excluding China) and in the Indomalayan realm. These bugs prefers heaths, hedge rows and meadows (hence the species name ''pratensis'', meaning ''of a meadow''). Description ''Lygus pratensis'' can reach a length of in males, of in females. The color pattern and markings of these plant bugs vary greatly. Color may be green, brown or reddish. Usually the males are light reddish-brown to dark red, while the females are green and brownish-colored. The body is oval in shape and slightly flattened. The scutellum is heart-shaped in both sexes. The wings are clearly visible, as they are not completely covered by the hemielytra. Eyes, legs and antennae are usually reddish. These bugs can be identified mainly on the basis of the fine details of the corium. This species is very similar to ''Lygus wagneri'' ...

Metamorphosis
Metamorphosis is a biological process by which an animal physically develops including birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior. Animals can be divided into species that undergo complete metamorphosis (" holometaboly"), incomplete metamorphosis ("hemimetaboly"), or no metamorphosis (" ametaboly"). Scientific usage of the term is technically precise, and it is not applied to general aspects of cell growth, including rapid growth spurts. Generally organisms with a larva stage undergo metamorphosis, and during metamorphosis the organism loses larval characteristics. References to "metamorphosis" in mammals are imprecise and only colloquial, but historically idealist ideas of transformation ...

Tanacetum Vulgare
Tansy (''Tanacetum vulgare'') is a perennial, herbaceous flowering plant in the genus ''Tanacetum'' in the aster family, native to temperate Europe and Asia. It has been introduced to other parts of the world, including North America, and in some areas has become invasive. It is also known as common tansy, bitter buttons, cow bitter, or golden buttons. The Latin word ''vulgare'' means "common". Description Tansy is a flowering herbaceous plant with finely divided compound leaves and yellow, button-like flowers. It has a stout, somewhat reddish, erect stem, usually smooth, tall, and branching near the top. The leaves are alternate, long and are pinnately lobed, divided almost to the center into about seven pairs of segments, or lobes, which are again divided into smaller lobes having saw-toothed edges, giving the leaf a somewhat fern-like appearance. The roundish, flat-topped, button-like, yellow flower heads are produced in terminal clusters from mid-to-late summer. The ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Urtica Dioica
''Urtica dioica'', often known as common nettle, burn nettle, stinging nettle (although not all plants of this species sting) or nettle leaf, or just a nettle or stinger, is a herbaceous perennial flowering plant in the family Urticaceae. Originally native to Europe, much of temperate Asia and western North Africa, it is now found worldwide, including New Zealand and North America. The species is divided into six subspecies, five of which have many hollow stinging hairs called trichomes on the leaves and stems, which act like hypodermic needles, injecting histamine and other chemicals that produce a stinging sensation upon contact ("contact urticaria", a form of contact dermatitis). The plant has a long history of use as a source for traditional medicine, food, tea, and textile raw material in ancient (such as Saxon) and modern societies. Description ''Urtica dioica'' is a dioecious, herbaceous, perennial plant, tall in the summer and dying down to the ground in winter. ...

Rumex Obtusifolius
''Rumex obtusifolius'', commonly known as bitter dock, broad-leaved dock, bluntleaf dock, dock leaf, dockens or butter dock, is a perennial plant in the family Polygonaceae. It is native to Europe, but is found on all temperate continents. It is a highly invasive species in some zones, resulting from its abundant seed dispersal, adaptability to reproduce, aggressive roots, ability to tolerate extreme climates, and hardiness. Etymology The name, ''Rumex obtusifolius'', was assigned by Carl Linnaeus in the 18th century, and has remained unchanged, although there are numerous subspecies. ''Rumex'' was Pliny's name for sorrel,Gledhill, David (2008). "The Names of Plants". Cambridge University Press. (hardback), (paperback). pp 277, 335 while ''obtusifolius'' means 'obtuse-leaved' (obtuse + foliage). Description ''Rumex obtusifolius'' is a perennial herbaceous flowering plant that grows to a height of . It is easily recognizable by its very large oval leaves with cordat ...

Hieracium
''Hieracium'' (), known by the common name hawkweed and classically as (from ancient Greek ιεράξ, 'hawk'), is a genus of flowering plant in the family Asteraceae, and closely related to dandelion (''Taraxacum''), chicory ('' Cichorium''), prickly lettuce (''Lactuca'') and sow thistle (''Sonchus''), which are part of the tribe Cichorieae. Hawkweeds, with their 10,000+ recorded species and subspecies, do their part to make Asteraceae the second largest family of flowering plants. Some botanists group all these species or subspecies into approximately 800 accepted species, while others prefer to accept several thousand species. Since most hawkweeds reproduce exclusively asexually by means of seeds that are genetically identical to their mother plant (apomixis or agamospermy), clones or populations that consist of genetically identical plants are formed and some botanists (especially in UK, Scandinavia and Russia) prefer to accept these clones as good species (arguing t ...

Hypericum
''Hypericum'' is a genus of flowering plants in the family Hypericaceae (formerly considered a subfamily of Clusiaceae). The genus has a nearly worldwide distribution, missing only from tropical lowlands, deserts and polar regions. Many ''Hypericum'' species are regarded as invasive species and noxious weeds. All members of the genus may be referred to as St. John's wort, and some are known as goatweed. The white or pink flowered marsh St. John's worts of North America and eastern Asia are generally accepted as belonging to the separate genus ''Triadenum'' Raf. ''Hypericum'' is unusual for a genus of its size because a worldwide taxonomic monograph was produced for it by Norman Robson (working at the Natural History Museum, London). Robson recognizes 36 sections within ''Hypericum''. Description ''Hypericum'' species are quite variable in habit, occurring as trees, shrubs, annuals, and perennials. Trees in the sense of single stemmed woody plants are rare, as most woody s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.
