Sheet Weaver
Linyphiidae, spiders commonly known as sheet weavers (from the shape of their webs), or money spiders (in the United Kingdom, Ireland, Australia, New Zealand, and in Portugal, from the superstition that if such a spider is seen running on you, it has come to spin you new clothes, meaning financial good fortune) is a family of very small spiders comprising 4706 described species in 620 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly understood due to their small body size and wide distribution, new genera and species are still being discovered throughout the world. The newest such genus is ''Himalafurca'' from Nepal, formally described in April 2021 by Tanasevitch. Since it is so difficult to identify such tiny spiders, there are regular changes in taxonomy as species are combined or divided. * Money spiders are known for drifting through the air via a technique termed “ballooning”. * Within the agric ...

Ballooning (spider)
Ballooning, sometimes called kiting, is a process by which spiders, and some other small invertebrates, move through the air by releasing one or more gossamer threads to catch the wind, causing them to become airborne at the mercy of air currents and electric fields. A 2018 study concluded that electric fields provide enough force to lift spiders in the air, and possibly elicit ballooning behavior. This is primarily used by spiderlings to disperse; however, larger individuals have been observed doing so as well. The spider climbs to a high point and takes a stance with its abdomen to the sky, releasing fine silk threads from its spinneret until it becomes aloft. Journeys achieved vary from a few metres to hundreds of kilometres. Even atmospheric samples collected from balloons at five kilometres altitude and ships mid-ocean have reported spider landings. Ballooning can be dangerous (due to predators, and due to the unpredictable nature of long-distance ballooning, which may brin ...

Filmy Dome Spider
The filmy dome spider (''Neriene radiata'') is a sheet weaver: a spider in the family Linyphiidae with a holarctic distribution. These spiders construct a dome of fine spider silk and hang upside-down under it, waiting for their prey. It is a preferential host for the kleptoparasitic ''Argyrodes trigonum ''Argyrodes'', also called dewdrop spiders, is a genus of comb-footed spiders that was first described by Eugène Louis Simon in 1864.

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Dwarf Spider
Erigoninae are the largest subfamily of sheet weavers (Linyphiidae), which is itself the second largest spider family. In the United States they are known as dwarf spiders, while they are called money spiders in England. The exact taxonomic limits of the subfamily are not yet known.Hormiga 2000 Erigoninae are the most numerous of the sheet weavers, with more than 2,000 described species. Many species live in leaf litter and build minute sheet webs. These spiders probably are more important as members of the beneficial complex of predators in agroecosystems than is generally known. indicates that Erigone atra (23.5%) Tenuiphantes tenuis (20.1%), Oedothorax apicatus (14.5%) are the most active species in agricultural fields. One species, '' Atypena formosana'' lives in colonies in wetland habitats, where it builds nets just above the water line in rice fields to hunt planthopper nymphs. The most well-known genus is '' Erigone''. Description Most are very small (some less than 1& ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheetweb Spider
Stiphidiidae, also called sheetweb spiders, is a family of araneomorph spiders first described in 1917. Most species are medium size ('' Stiphidion facetum'' is about long) and speckled brown with long legs. All members of this family occur in New Zealand and Australia except for ''Asmea''. They build a horizontal sheet-like web under rocks, hence the name "sheetweb spiders". The largest of New Zealand's species is '' Cambridgea foliata'', with a body length up to and a span of up to . Hikers and trampers often find their sheet-like webs that can be up to across, but the spider itself is nocturnal, spending the day time inside its web tunnel. It can also be found in gardens and males may enter human homes. Their large size, including mouth parts up to long, may be intimidating, but it is considered harmless to humans and bites are extremely rare. Genera , the World Spider Catalog accepts the following genera: *''Aorangia'' Forster & Wilton, 1973 — New Zealand *''Asmea' ...

Pimoidae
Pimoidae is a small family of araneomorph spiders first described by J. Wunderlich in 1986. As re-circumscribed in 2021, it is monophyletic, and contained 85 species in two genera. It is closely related to the Linyphiidae, and is sometimes treated as synonymous with that family. The species ''Pimoa cthulhu'', described by Gustavo Hormiga in 1994, is named for Howard Phillips Lovecraft's mythological deity Cthulhu. Distribution The ancestors of the family are thought to have been widely distributed across the Palearctic, Nearctic and Sino-Japanese regions, but species now have a more fragmented distribution. Genera and species , the World Spider Catalog accepted the following genera and species: *'' Nanoa'' Hormiga, Buckle & Scharff, 2005 **'' Nanoa enana'' Hormiga, Buckle & Scharff, 2005 — USA *'' Pimoa'' Chamberlin & Ivie, 1943 — North America, Asia, Europe **'' Pimoa altioculata'' (Keyserling, 1886) – USA, Canada **'' Pimoa anatolica'' Hormiga, 1994 – China **'' P ...

Spider
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 ...

Goldcrest
The goldcrest (''Regulus regulus'') is a very small passerine bird in the kinglet family. Its colourful golden crest feathers, as well as being called the "king of the birds" in European folklore, gives rise to its English and scientific names. The scientific name, ''R. regulus'', means king or knight. Several subspecies are recognised across the very large distribution range that includes much of the Palearctic and the islands of Macaronesia and Iceland. Birds from the north and east of its breeding range migrate to winter further south. This kinglet has greenish upper-parts, whitish under-parts, and has two white wingbars. It has a plain face contrasting black irises and a bright head crest, orange and yellow in the male and yellow in the female, which is displayed during breeding. It superficially resembles the common firecrest (''Regulus ignicapilla''), which largely shares its European range, but the latter's bronze shoulders and strong face pattern are distinctive. T ...
