Andrena Helvola
''Andrena helvola '', the coppice mining bee, is a Palearctic species of mining bee from the genus ''Andrena''. Description ''Andrena helvola'' is a medium sized bee, the females are larger than the males with a forewing length of while in the smaller males the forewings are with the larger males being more robust with bigger heads than the smaller individuals. The females have a pile of reddish-brown hair on the top of the thorax with a rather thick pile of orange or yellowish hair on the first and second tergites and a short grey pile on the third and fourth tergites. Taxonomy ''Andrena helvola'' was first formally described in 1758 as ''Apis helvola'' by Carl Linnaeus. In 1775 Fabricius described the genus ''Andrena'' and in 1912 Viereck designated ''A. helvola'' as its type species. Distribution and habitat ''Andrena helvola'' is found in the Western Palearctic from Great Britain to Russia, north to southern Scandinavia and south to the Pyrenees, Alps, the Balkans and A ...

Geography Of Denmark
Denmark is a Nordic country located in Northern Europe. It consists of the Jutland Peninsula and several islands in the Baltic Sea, referred to as the Danish Archipelago. Denmark is located southwest of Sweden and due south of Norway and is bordered by the German state (and former possession) Schleswig-Holstein to the south, on Denmark's only land border, 68 kilometres (42 miles) long. Denmark borders both the Baltic and North seas along its tidal shoreline. Denmark's general coastline is much shorter, at , as it would not include most of the 1,419 offshore islands (each defined as exceeding 100 square metres in area) and the 180-kilometre long Limfjorden, which separates Denmark's second largest island, North Jutlandic Island, 4,686 km2 in size, from the rest of Jutland. No location in Denmark is further from the coast than . The land area of Denmark is estimated to be . However, it cannot be stated exactly since the ocean constantly erodes and adds material to the coastline, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balkans
The Balkans ( ), also known as the Balkan Peninsula, is a geographical area in southeastern Europe with various geographical and historical definitions. The region takes its name from the Balkan Mountains that stretch throughout the whole of Bulgaria. The Balkan Peninsula is bordered by the Adriatic Sea in the northwest, the Ionian Sea in the southwest, the Aegean Sea in the south, the Turkish Straits in the east, and the Black Sea in the northeast. The northern border of the peninsula is variously defined. The highest point of the Balkans is Mount Musala, , in the Rila mountain range, Bulgaria. The concept of the Balkan Peninsula was created by the German geographer August Zeune in 1808, who mistakenly considered the Balkan Mountains the dominant mountain system of Southeast Europe spanning from the Adriatic Sea to the Black Sea. The term ''Balkan Peninsula'' was a synonym for Rumelia in the 19th century, the European provinces of the Ottoman Empire. It had a ge ...

Hymenoptera Of Europe
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Univoltine
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. north ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dandelion
''Taraxacum'' () is a large genus of flowering plants in the family Asteraceae, which consists of species commonly known as dandelions. The scientific and hobby study of the genus is known as taraxacology. The genus is native to Eurasia and North America, but the two most commonplace species worldwide, ''Taraxacum officinale, T. officinale'' (the common dandelion) and ''Taraxacum erythrospermum, T. erythrospermum'' (the red-seeded dandelion), were introduced from Europe into North America, where they now propagate as wildflowers. Both species are List of leaf vegetables, edible in their entirety. The common name ''dandelion'' ( , from French language, French , meaning 'lion's tooth') is also given to specific members of the genus. Like other members of the family Asteraceae, they have very small flowers collected together into a composite Head (botany), flower head. Each single flower in a head is called a ''floret''.

''Salix alba'', the white willow, is a species of willow native to Europe and western and central Asia.Meikle, R. D. (1984). ''Willows and Poplars of Great Britain and Ireland''. BSBI Handbook No. 4. .Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins . The name derives from the white tone to the undersides of the leaves. It is a medium-sized to large deciduous tree growing up to 10–30 m tall, with a trunk up to 1 m diameter and an irregular, often-leaning crown. The bark is grey-brown, and deeply fissured in older trees. The shoots in the typical species are grey-brown to green-brown. The leaves are paler than most other willows, due to a covering of very fine, silky white hairs, in particular on the underside; they are 5–10 cm long and 0.5–1.5 cm wide. The flowers are produced in catkins in early spring, and pollinated by insects. It is dioecious, with male and female catkins on separate trees; the male catkins are 4–5 cm long, t ...

Wood Spurge
''Euphorbia amygdaloides'', the wood spurge, is a species of flowering plant in the family Euphorbiaceae, native to woodland locations in Europe, Turkey and the Caucasus. It is a bushy evergreen perennial, growing to a height of , with dark green slightly hairy leaves about long. The complex green-yellow inflorescence (cyathium), typical of ''Euphorbia'', appears in late spring and early summer. It is among the few plants that thrive in the dry shade of trees, where it is used as groundcover. It spreads rapidly by underground rhizomes and can become invasive, though relatively easy to remove. One form known is ''Euphorbia'' ‘Efanthia’. The subspecies ''E. amygdaloides'' subsp.

Stylops Nevinsonii
''Stylops'' is a genus of obligately endoparasitic insects in the family Stylopidae. Hosts are typically members of the order Hymenoptera. The name "stylops", used without a capital "s", refers as a common name to any member of the order Strepsiptera, and not only the genus ''Stylops''. Description Males are 2-3 mm long and black with white wings. Females have no limbs and are only seen from their head and thorax poking out of the host bee. Larvae are triungulin. Life cycle ''Stylops'' larvae emerge from their host bee while the host gathers pollen from flowers. The larvae then attach to other bees in order to be carried back to the nest. At the nest, the ''Stylops'' larvae enter the bodies of bee larvae and develop along with their host. Adult males leave their hosts to mate with females, who remain inside their host and hatch their eggs there.
