Arachnospila Trivialis
''Arachnospila trivialis'' is a widespread spider wasp of sandy soil areas of the Palaearctic. Description A medium-sized red and black spider wasp. The males have a quite distinctive genital plate, but females are very similar to other species assigned to the subgenus ''Ammosphex'', such as '' A. anceps'' and considerable care is required to identify them. Distribution Northern and central Europe, including southern and western areas of Great Britain, and across Asia to the Pacific. Biology ''A trivialis'' is single brooded, flying from May to August. The only confirmed prey are spiders of the genus '' Xysticus'' and it may prey on wolf spiders of the family Lycosidae too. Apparently little appears to be known about ''A trivialis'' nesting biology, but like other ''Arachnospila'' species it is likely to excavate a nest in loose sand having already paralysed a spider and concealed it in nearby vegetation. Adults have been observed to visit the flowers of wild parsnip Wild p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anders Gustaf Dahlbom
Anders Gustaf Dahlbom (3 March 1806 – 3 May 1859) was a Swedish entomologist. Dahlbom was born in Härberga parish in Östergötland County, son of a military surgeon. He matriculated at Lund University in 1825, completed his filosofie magister degree in 1829, became a docent of natural history in 1830, acting adjunct of entomology in 1841, adjunct in 1843 and keeper of the Entomological collections and professor extraordinary in 1857. Supported by public funds, he made several research journeys, especially to northern Sweden and the mountain regions, where he first accompanied his teacher, the dipterologist Johan Wilhelm Zetterstedt Johan Wilhelm Zetterstedt (20 May 1785 – 23 December 1874) was a Swedish naturalist who worked mainly on Diptera and Hymenoptera. Biography Zetterstedt studied at the University of Lund, where he was a pupil of Anders Jahan Retzius. He rec ..., as well as to other parts of the country and abroad, and published his observations in vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spider Wasp
Wasps in the family Pompilidae are commonly called spider wasps, spider-hunting wasps, or pompilid wasps. The family is cosmopolitan, with some 5,000 species in six subfamilies. Nearly all species are solitary (with the exception of some group-nesting Ageniellini), and most capture and paralyze prey, though members of the subfamily Ceropalinae are kleptoparasites of other pompilids, or ectoparasitoids of living spiders. In South America, species may be referred to colloquially as or , though these names can be generally applied to any very large stinging wasps. Furthermore, in some parts of Venezuela and Colombia, it is called , or "horse killers", while in Brazil some particular bigger and brighter species of the general kind might be called /, or "throat locker". Morphology Like other strong fliers, pompilids have a thorax modified for efficient flight. The metathorax is solidly fused to the pronotum and mesothorax; moreover, the prothorax is best developed in Pompilidae a ...

Palaearctic
The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Siberian region; the Mediterranean Basin; the Sahara and Arabian Deserts; and Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. The term 'Palearctic' was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/Afrotropic, Indian/Indomalayan, Australasian, Nearctic, and Neotropical. The six indicated general groupings of fauna, based on shared biogeography and large-scale geographic barriers to migration. Alfred Wallace ad ...

Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostylis'', ...

Arachnospila Anceps
''Arachnospila anceps'' is one of the more common spider wasps of western Europe. Description ''A. anceps'' is a medium-sized, black and red spider wasp. Distribution This species is found in northern and central Europe, including most of Britain and Ireland, and in Asia east to Mongolia. Biology The flight period is May to September and the species is probably univoltine. A wide range of spiders are taken as prey; the families Lycosidae, Clubionidae and Thomisidae have been recorded and Gnaphosidae and Agelenidae The Agelenidae are a large family of spiders in the suborder Araneomorphae. Well-known examples include the common "grass spiders" of the genus ''Agelenopsis''. Nearly all Agelenidae are harmless to humans, but the bite of the hobo spider (''Erat ... are also possible prey. The spider is paralysed before being dragged backwards to the nest site where it is hidden on a plant while the burrow is rapidly excavated. It occurs in a variety of habitats and on most soi ...

Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...

Xysticus
''Xysticus'' is a genus of ground crab spiders described by C. L. Koch in 1835, belonging to the order Araneae, family Thomisidae. The genus name is derived from the Ancient Greek root ''xyst'', meaning "scraped, scraper". Description ''Xysticus'' and '' Coriarachne'' are dark brown or reddish-brown crab spiders often encountered on weeds or trees. While similar to the 'flower spiders', they tend to have shorter, sturdier legs. Many, but not all, species have abdomens more patterned than most ''Thomisus'' species, rather like some of the ''Synema'' species. Some however, that are more terrestrial, resemble earth in colour and texture. Most species of the genus Xysticus are small to medium sized spiders. They show a sexual dimorphism in size. Females of typical species reach a maximum of of body length, while their males are about long, about half the size of the females. The basic colour of these species is usually brown, beige or gray. The prosoma is sometimes slightly smal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycosidae
Wolf spiders are members of the family Lycosidae (). They are robust and agile hunters with excellent eyesight. They live mostly in solitude, hunt alone, and do not spin webs. Some are opportunistic hunters, pouncing upon prey as they find it or chasing it over short distances; others wait for passing prey in or near the mouth of a burrow. Wolf spiders resemble nursery web spiders (family Pisauridae), but wolf spiders carry their egg sacs by attaching them to their spinnerets, while the Pisauridae carry their egg sacs with their chelicerae and pedipalps. Two of the wolf spider's eight eyes are large and prominent; this distinguishes them from nursery web spiders, whose eyes are all of roughly equal size. This can also help distinguish them from the similar-looking grass spiders. Description The many genera of wolf spiders range in body size (legs not included) from less than . They have eight eyes arranged in three rows. The bottom row consists of four small eyes, the middle ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parsnip
The parsnip (''Pastinaca sativa'') is a root vegetable closely related to carrot and parsley, all belonging to the flowering plant family Apiaceae. It is a biennial plant usually grown as an annual. Its long taproot has cream-colored skin and flesh, and, left in the ground to mature, it becomes sweeter in flavor after winter frosts. In its first growing season, the plant has a rosette of pinnate, mid-green leaves. If unharvested, in its second growing season it produces a flowering stem topped by an umbel of small yellow flowers, later producing pale brown, flat, winged seeds. By this time, the stem has become woody and the tap root inedible. The parsnip is native to Eurasia; it has been used as a vegetable since antiquity and was cultivated by the Romans, although some confusion exists between parsnips and carrots in the literature of the time. It was used as a sweetener before the arrival of cane sugar in Europe. Parsnips are usually cooked, but can also be eaten raw. T ...

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] |
