Epeolus Cruciger
''Epeolus cruciger'', the red-thighed epeolus, is a species of cuckoo bee from the family Apidae. It is endemic to Europe, where its main host is the common colletes (''Colletes succintus''), although other species of '' Colletes'' mining bees have been recorded as hosts. Description ''Epeolus cruciger'' is a small bee in which the females have a reddish scutellum and tend to have entirely red legs. The fifth sternite is straight when viewed from the side and from below it is noticeably wider than it is long. The abdomen is nearly completely reddish. The males have a dark scutellum (scutellum dark) usually have a reddish pygidium. The abdomen is black with large, paired whitish patches of flattened hair on each side. They are 6-8mm in length. Distribution ''Epeolus cruciger'' is found in southern and central Europe as far north as Finland and is thought to be endemic to Europe. In Britain it is widespread in the southern part but becomes scarcer in the north, with one old ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georg Wolfgang Franz Panzer
Georg Wolfgang Franz Panzer (31 May 1755 – 28 June 1829) was a German botanist and entomologist. He was born at Etzelwang in the Upper Palatinate and died at Hersbruck, near Nuremberg. He was the son of (the elder, 1729-1805), one of the most distinguished and productive of German bibliographers, whose ''Annales Typographici'' were published between 1793 and 1803.G.W. Panzer, ''Annales Typographici ab Artis Inventae Origine usque ad annum MDXXXVI'', 11 Vols (Impensis Joannis Eberhardi Zeh, Bibliopolae, Norimbergae 1793-1803). A physician, he practised at Hersbruck. A celebrated botanist, he had a very species-rich herbarium. He also assembled a very important insect collection which was the basis of a vast work ''Faunae insectorum germanicae initia'' (Elements of the insect fauna of Germany), published at Nuremberg between 1796 and 1813.

Senecio Jacobaea
''Jacobaea vulgaris'', syn. ''Senecio jacobaea'', is a very common wild flower in the family Asteraceae that is native to northern Eurasia, usually in dry, open places, and has also been widely distributed as a weed elsewhere. Common names include ragwort, common ragwort, smegplant, stinking willie, tansy ragwort, benweed, St. James-wort, stinking nanny/ninny/willy, staggerwort, dog standard, cankerwort, stammerwort. In the western United States it is generally known as tansy ragwort, or tansy, though its resemblance to the true tansy is superficial. In some countries it is an invasive species and regarded as a noxious weed. In the UK, where it is native, it is often unwanted because of its toxic effect for cattle and horses, but it is also valued for its nectar production which feeds insect pollinators and its ecological importance is thus considered significant. Description The plant is generally considered to be biennial but it has the tendency to exhibit perennial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mentha
''Mentha'' (also known as mint, from Greek , Linear B ''mi-ta'') is a genus of plants in the family Lamiaceae (mint family). The exact distinction between species is unclear; it is estimated that 13 to 24 species exist. Hybridization occurs naturally where some species' ranges overlap. Many hybrids and cultivars are known. The genus has a subcosmopolitan distribution across Europe, Africa - (Southern Africa), Asia, Australia - Oceania, North America and South America. Its species can be found in many environments, but most grow best in wet environments and moist soils. Description Mints are aromatic, almost exclusively perennial herbs. They have wide-spreading underground and overground stolons and erect, square, branched stems. Mints will grow 10–120 cm (4–48 inches) tall and can spread over an indeterminate area. Due to their tendency to spread unchecked, some mints are considered invasive. The leaves are arranged in opposite pairs, from oblong to lanceol ...

Leontodon
''Leontodon'' is a genus of plants in the tribe Cichorieae within the family Asteraceae, commonly known as hawkbits. Their English name derives from the mediaeval belief that hawks ate the plant to improve their eyesight. Although originally only native to Eurasia and North Africa, some species have since become established in other countries, including the United States and New Zealand. Recent research has shown that the genus ''Leontodon'' in the traditional delimitation is polyphyletic. Therefore, the former ''Leontodon'' subgenus ''Oporinia'' was raised to generic level. According to the nomenclatural rules the name '' Scorzoneroides'' has priority at generic level and therefore, the members of ''Leontodon'' subgenus ''Oporinia'' were transferred to the re-erected genus ''Scorzoneroides''. Ecology Seeds of ''Leontodon'' species are an important food source for certain bird species. Uses In Crete, the species ''Leontodon tuberosus'' which is called ('), (') or (') has i ...

Trifolium
Clover or trefoil are common names for plants of the genus ''Trifolium'' (from Latin ''tres'' 'three' + ''folium'' 'leaf'), consisting of about 300 species of flowering plants in the legume or pea family Fabaceae originating in Europe. The genus has a cosmopolitan distribution with highest diversity in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics. They are small annual, biennial, or short-lived perennial herbaceous plants, typically growing up to 30 cm tall. The leaves are trifoliate (rarely quatrefoiled; see four-leaf clover), monofoil, bifoil, cinquefoil, hexafoil, septfoil, etcetera, with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx. Other closely related genera often called clovers include ''Melilotus'' (sweet clover) and '' Medicago'' (alfalfa or Calvary clover ...

Kleptoparasitism
Kleptoparasitism (etymologically, parasitism by theft) is a form of feeding in which one animal deliberately takes food from another. The strategy is evolutionarily stable when stealing is less costly than direct feeding, which can mean when food is scarce or when victims are abundant. Many kleptoparasites are arthropods, especially bees and wasps, but including some true flies, dung beetles, bugs, and spiders. Cuckoo bees are specialized kleptoparasites which lay their eggs either on the pollen masses made by other bees, or on the insect hosts of parasitoid wasps. They are an instance of Emery's rule, which states that insect social parasites tend to be closely related to their hosts. The behavior occurs, too, in vertebrates including birds such as skuas, which persistently chase other seabirds until they disgorge their food, and carnivorous mammals such as spotted hyenas and lions. Other species opportunistically indulge in kleptoparasitism. Strategy Kleptoparasitism is a fe ... [...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] |
Calluna Vulgaris
''Calluna vulgaris'', common heather, ling, or simply heather, is the sole species in the genus ''Calluna'' in the flowering plant family Ericaceae. It is a low-growing evergreen shrub growing to tall, or rarely to and taller, and is found widely in Europe and Asia Minor on acidic soils in open sunny situations and in moderate shade. It is the dominant plant in most heathland and moorland in Europe, and in some bog vegetation and acidic pine and oak woodland. It is tolerant of grazing and regenerates following occasional burning, and is often managed in nature reserves and grouse moors by sheep or cattle grazing, and also by light burning. ''Calluna'' was separated from the closely related genus ''Erica'' by Richard Anthony Salisbury, who devised the generic name ''Calluna'' probably from the Ancient Greek (), "beautify, sweep clean", in reference to its traditional use in besoms. The specific epithet ''vulgaris'' is Latin for 'common'. ''Calluna'' is differentiated from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moorland
Moorland or moor is a type of habitat found in upland areas in temperate grasslands, savannas, and shrublands and montane grasslands and shrublands biomes, characterised by low-growing vegetation on acidic soils. Moorland, nowadays, generally means uncultivated hill land (such as Dartmoor in South West England), but also includes low-lying wetlands (such as Sedgemoor, also South West England). It is closely related to heath, although experts disagree on what precisely distinguishes these types of vegetation. Generally, moor refers to highland and high rainfall zones, whereas heath refers to lowland zones which are more likely to be the result of human activity. Moorland habitats mostly occur in tropical Africa, northern and western Europe, and neotropical South America. Most of the world's moorlands are diverse ecosystems. In the extensive moorlands of the tropics, biodiversity can be extremely high. Moorland also bears a relationship to tundra (where the subsoil is permafros ...
