Volucella Pellucens
''Volucella pellucens'', the pellucid fly, is a hoverfly. Distribution and habitat This species occurs in much of Europe, and across the Palearctic to Japan. The adult ''V. pellucens'' is usually found in woodlands and wooded hedgerows, but will enter gardens. Description ''Volucella pellucens'' is about 13–17 mm in length, with a wing length about 10–15.5 mm.Stuart Ball, S. G. Ball, Roger MorriBritain's Hoverflies: An Introduction to the Hoverflies of Britain/ref> These hoverflies have a broad, mainly black body, but the front part of their abdomens have a broad, yellow band, giving them the appearance of a bee or wasp. Their two wings are transparent, as with most flies, but the leading edge is amber, with a brown patch on each wing. The mimicry of bees or wasps in shape and colouration is shown by other hoverflies, which is thought to protect against falling prey to birds and other insectivores that avoid eating true wasps because of their stings.

Volucella
''Volucella'' is a genus of large, broad-bodied, dramatic hover-flies. They have distinctive plumose aristae and the face is extended downward. They are strongly migratory and males are often territorial. Adults feed on nectar of flowers and are often seen sunning on leaves. The larvae of most species live in nests of bumblebees and social wasps, where they are detritivores and larval predators.

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] |
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 large ...

List Of Hoverfly Species Recorded In Britain
The following is a list of hoverfly (Syrphidae) species recorded in Great Britain. Alan Stubbs and Steven Falk, in their 1983 work ''British Hoverflies'', divided the family into subfamilies and tribes. These subdivisions are now believed to be, to some extent, artificial groupings, not reflecting the evolutionary relationships within the family, so in need of revision. As no replacement system is yet in place, though, these groupings are retained in this list. The six unnamed species listed in Stubbs and Falk (1983) are not included below. Subfamily Syrphinae Tribe Bacchini (incorporating Melanostomatini) ;''Baccha'' :* ''Baccha elongata'' (syn. ''B. obscuripennis'') ;''Melanostoma'' :* ''Melanostoma dubium'' :* '' Melanostoma mellinum'' :* ''Melanostoma scalare'' ;''Platycheirus'' :*Subgenus ''Pachysphyria'' :** ''Platycheirus ambiguus'' :*Subgenus ''Platycheirus'' :** ''Platycheirus albimanus'' :**''Platycheirus amplus'' :** ''Platycheirus angustatus'' :** ''Platycheiru ...

Pupa
A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in insects with complete metamorphosi ...

German Wasp
''Vespula germanica'', the European wasp, German wasp, or German yellowjacket, is a species of wasp found in much of the Northern Hemisphere, native to Europe, Northern Africa, and temperate Asia. It has spread and become well-established in many other places, including North America, South America (Argentina and Chile), Australia, South Africa, and New Zealand. German wasps are part of the family Vespidae and are sometimes mistakenly referred to as paper wasps because they build grey paper nests, although strictly speaking, paper wasps are part of the subfamily Polistinae. In North America, they are also known as yellowjackets. Taxonomy and phylogeny ''Vespula germanica'' belongs to the genus ''Vespula'', which includes various species of social wasps that are found throughout the Northern Hemisphere. In North America, these wasps are most commonly known as yellowjackets, but this name also applies to species within the sister genus ''Dolichovespula''. Members of ''Vespula'' a ...

Vespula Vulgaris
''Vespula vulgaris'', known as the Common wasp, is a species found in regions that include the United Kingdom, Ireland, Germany, India, China, New Zealand and Australia. It is sometimes known in English as the European wasp, but the same name is used for the species ''Vespula germanica'' or German wasp. In 2010, the ostensible ''Vespula vulgaris'' wasps in North America were found to be a different species, ''Vespula alascensis''. Basic features ''Vespula vulgaris'' is a eusocial vespid that builds its tan paper nest in or on a structure capable of supporting it. A founding queen searches for a hollow tree, wall cavity, rock crevice, or even a mammal-made hole to build a nest. One colony cycle lasts for about 6–11 months and each colony cycle produces around 3000–8000 larvae. The extraordinary adaptation skills of ''V. vulgaris'' enable it to live in a wide range of habitats, from very humid areas to artificial environments such as gardens and human structures.

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. ...

Chamerion Angustifolium
''Chamaenerion angustifolium'' is a Perennial plant, perennial Herbaceous plant, herbaceous flowering plant in the willowherb family Onagraceae. It is known in North America as fireweed, in some parts of Canada as great willowherb, in Britain and Ireland as rosebay willowherb. In the United Kingdom it is also known as bombweed, as a result of its rapid appearance on city bomb sites during the Blitz of World War II; the plant is also traditionally known as Anthony the Great, Saint Anthony's laurel. It is also known by the Synonym (taxonomy), synonyms ''Chamerion angustifolium'' and ''Epilobium angustifolium''. It is native throughout the temperate Northern Hemisphere, including large parts of the boreal forests. Description The reddish stems of this herbaceous perennial are usually simple, erect, smooth, high with scattered alternate leaves. The leaves are spirally arranged, entire, narrowly lanceolate, and pinnately veined, the secondary leaf veins anastomosing, joining to ...

Succisa Pratensis
''Succisa pratensis'', also known as devil's-bit or devil's-bit scabious, is a flowering plant in the honeysuckle family Caprifoliaceae. It differs from other similar species in that it has four-lobed flowers, whereas small scabious and field scabious have five lobes and hence it has been placed in a separate genus in the same family. It also grows on damper ground. Name Species of scabious were used to treat scabies, and other afflictions of the skin including sores caused by the bubonic plague. The word scabies comes from the Latin word for "scratch" (scabere). The short black root was in folk tales bitten off by the devil, angry at the plant's ability to cure these ailments, in anger against the Virgin Mary, or as part of some 'devilish plot'. The Latin binomial nomenclature, specific epithet ''pratensis'' literally means "of the meadow". Description ''Succisa pratensis'' is a herbaceous perennial plant, perennial up to 1m tall, growing from a basal rosette of simple or d ...

Valeriana Officinalis
Valerian (''Valeriana officinalis'', Caprifoliaceae) is a perennial flowering plant native to Europe and Asia. In the summer when the mature plant may have a height of , it bears sweetly scented pink or white flowers that attract many fly species, especially hoverflies of the genus ''Eristalis''. It is consumed as food by the larvae of some Lepidoptera (butterfly and moth) species, including the grey pug. Crude extract of valerian root may have sedative and anxiolytic effects, and is commonly sold in dietary supplement capsules to promote sleep, but there is insufficient clinical evidence that it is effective for this purpose. Its roots and leaves cause a catnip-like response in cats. History Valerian has been used as a herb in traditional medicine since at least the time of ancient Greece and Rome. Hippocrates described its properties, and Galen later prescribed it as a remedy for insomnia. In medieval Sweden, it was sometimes placed in the wedding clothes of the groom to war ...
