Agroeca Brunnea
''Agroeca brunnea'' is a species of spider in the family Liocranidae. It is found in the Palearctic realm and was first described by John Blackwall in 1833. The distinctive egg sacs are known colloquially as 'fairy lamps' and the spider itself is sometimes called the 'fairy lamp spider'.

John Blackwall
John Blackwall (20 January 1790 – 11 May 1881) was an English naturalist with a particular interest in spiders. Life Blackwall was born in Manchester on 20 January 1790. He lived at Hendre House near Llanrwst in north Wales from 1833 until his death. He was interested in nature from an early age, first in birds and then spiders, on which he published his first article in 1827. He published ''A History of the Spiders of Great Britain and Ireland'' (2 volumes, 1861–1864, Ray Society), which included accounts of 304 species and gave the first adequate descriptions of British spiders. Ten of the plates included were by Octavius Pickard-Cambridge and twelve were by the Irish naturalist Robert Templeton. He died 11 May 1881. Correspondence with Charles Darwin Blackwall wrote four letters on the subject of spiders to Charles Darwin, dated 12 February 1868, 18 February 1868, 10 August 1869 and 8 September 1869. They survive in the Darwin Archive at Cambridge University Library. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liocranidae
Liocranidae is a family of araneomorph spiders first described by Eugène Simon in 1897. They are one of several groups called "sac spiders". The holarctic genus '' Agroeca'' is the best-known, but it also includes various genera of more obscure spiders that still lack a diagnosis. Two species in the North American genus ''Neoanagraphis'' are found in the extremely dry conditions in the Mojave, Sonoran and Chihuahuan deserts. Females live in animal burrows while males wander and are the ones most often caught in pitfall traps. Genera , the World Spider Catalog accepts the following genera: *''Agraecina'' Simon, 1932 — Europe, Africa, Kazakhstan *'' Agroeca'' Westring, 1861 — Asia, Europe, Africa, South America, North America *''Andromma'' Simon, 1893 — Africa *''Apostenus'' Westring, 1851 — Africa, United States, Europe *''Arabelia'' Bosselaers, 2009 — Greece, Turkey *''Argistes'' Simon, 1897 — Sri Lanka *''Coryssiphus'' Simon, 1903 — South Africa *''Cteniogaster ...

Palearctic Realm
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 ...

American Museum Of Natural History
The American Museum of Natural History (abbreviated as AMNH) is a natural history museum on the Upper West Side of Manhattan in New York City. In Theodore Roosevelt Park, across the street from Central Park, the museum complex comprises 26 interconnected buildings housing 45 permanent exhibition halls, in addition to a planetarium and a library. The museum collections contain over 34 million specimens of plants, animals, fossils, minerals, rocks, meteorites, human remains, and human cultural artifacts, as well as specialized collections for frozen tissue and genomic and astrophysical data, of which only a small fraction can be displayed at any given time. The museum occupies more than . AMNH has a full-time scientific staff of 225, sponsors over 120 special field expeditions each year, and averages about five million visits annually. The AMNH is a private 501(c)(3) organization. Its mission statement is: "To discover, interpret, and disseminate—through scientific research and ...

New York, NY
New York, often called New York City or NYC, is the List of United States cities by population, most populous city in the United States. With a 2020 population of 8,804,190 distributed over , New York City is also the List of United States cities by population density, most densely populated major city in the United States, and is more than twice as populous as second-place Los Angeles. New York City lies at the southern tip of New York (state), New York State, and constitutes the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the world by urban area, urban landmass. With over 20.1 million people in its metropolitan statistical area and 23.5 million in its combined statistical area as of 2020, New York is one of the world's most populous Megacity, megacities, and over 58 million people live within of the city.

Corinnidae
Corinnidae is a family of araneomorph spiders, sometimes called corinnid sac spiders. The family, like other "clubionoid" families, has a confusing taxonomic history. Once it was a part of the large catch-all taxon Clubionidae, now very much smaller. The original members of the family are apparently similar only in that they have eight eyes arranged in two rows, conical anterior spinnerets that touch and are generally wandering predators that build silken retreats, or sacs, usually on plant terminals, between leaves, under bark or under rocks. In 2014, Martín Ramírez recognized the family in a restricted sense, including only the subfamilies Corinninae and Castianeirinae. Two former subfamilies of the Corinnidae are now treated as separate families, Phrurolithidae and Trachelidae. As now recognized, Corinnidae contains 71 genera and over 800 species worldwide. Among the common genera are ''Castianeira'' (nearly world wide) and ''Corinna'' (widespread). Members of the genus ''C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiders Described In 1833
Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate th ...
