Trichonephila
''Trichonephila'' is a genus of orb-weaver spiders that was first described by Friedrich Dahl in 1911, as a subgenus of ''Nephila''. ''Trichonephila'' was elevated to the level of genus (new rank) by Kuntner ''et al.'' in 2019. The genus ''Trichonephila'' belongs to the Araneidae family, also known as the orb weavers. The family Araneidae belongs within the superfamily of Araneoidea, comprising 18 families. Araneidae family members can be identified by looking for three-clawed spiders that have eight eyes spanned across two sets which form a trapezoid shape, on webs with a sticky glue like feeling. The very diverse Araneidae family is most famously known for their elaborate webs they spin, which are webs made of concentric circles with spokes extending out from the center. In few species of the spiders, you can find a zigzag shape going down the center of the web. Identifying the species of these spiders is not easy with the eye alone, it breaks down into phylogenomic variations bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trichonephila Clavata
''Trichonephila clavata'', also known as the , is a member of the ''Trichonephila'' genus. The spider can be found throughout Japan (except Hokkaidō), Korea, Taiwan, China, and since 2020, much of northeastern Georgia (U.S.), Georgia and northwestern South Carolina in the United States. Due to its large size and the bright, unique colors of the female ''Trichonephila'', the spider is well-favored in Japan. In 2014, scientists confirmed the first known occurrence of ''T. clavata'' in North America. In 2019, this species was moved from the genus ''Nephila'' to ''Trichonephila''. ''T. clavatas congener ''Trichonephila plumipes'' is commonly found in Australia. It also was moved from ''Nephila'' to ''Trichonephila'', along with 10 other species. Characteristics ''Trichonephila clavata'' pass winter as eggs and scatter as tiny juveniles in the spring. The adult female's body size is 17–25 mm, while the male's is 7–10 mm. The web of females may reach several meters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichonephila Clavipes
''Trichonephila clavipes'' (formerly known as ''Nephila clavipes''), commonly known as the golden silk orb-weaver, golden silk spider, or banana spider (a name shared with Banana spider, several others), is an Orb-weaver spider, orb-weaving spider species which inhabits forests and wooded areas ranging from the Southern United States, southern US to Argentina. It is indigenous to both continental North America, North and South America. Known for the golden color of their silk, the large size of their females, and their distinctive red-brown and yellow coloring, ''T. clavipes'' construct large, asymmetrical circular webs attached to trees and low shrubs in woods to catch small- and medium-size flying prey, mostly insects. They are excellent web-builders, producing and utilizing seven different types of Spider silk, silk, and they subdue their prey by injecting them with venom, as opposed to related species which immobilize their prey by wrapping them in silk first. They are not kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichonephila Inaurata
''Trichonephila inaurata'', synonym ''Nephila inaurata'', commonly known as the red-legged golden orb-weaver spider or red-legged nephila, is a species of orb-weaver spider of the genus ''Trichonephila''. It is native to southern and East Africa, as well as several islands of the western Indian Ocean (Madagascar, the Seychelles, Réunion, Mauritius, Rodrigues). Web spinning and structure ''Trichonephila'' spiders produce large asymmetric orb webs up to in diameter. ''Trichonephila'' species remain in their webs permanently, so have a higher predation risk. The golden silk orb-weaver is named for the yellow color of the spider silk used to construct these webs. Yellow threads of their web shine like gold in sunlight. Carotenoids are the main contributors to this yellow color, but xanthurenic acid, two quinones, and an unknown compound may also aid in the color. Experimental evidence suggests that the silk's color may serve a dual purpose: sunlit webs ensnare bees that are attra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichonephila Fenestrata
''Trichonephilia fenestrata'' is a species of araneid spider known to be found in South Africa and Zambia. Males of this species often autotomize their legs as a counter adaptation to the sexual cannibalism Sexual cannibalism is when an animal, usually the female, cannibalizes its mate prior to, during, or after copulation.Polis, G.A. & Farley, R.D.

Nephila
''Nephila'' is a genus of araneomorph spiders noted for the impressive webs they weave. ''Nephila'' consists of numerous species found in warmer regions around the world. They are commonly called golden silk orb-weavers, golden orb-weavers, giant wood spiders, or banana spiders. Etymology The genus name ''Nephila'' is derived from Ancient Greek, meaning "fond of spinning", from the words νεῖν (''nein'') = to spin (related to ''nema'' νήμα "thread") + φίλος (''philos'') = "love". Description ''Nephila'' spiders vary from reddish to greenish yellow in color with distinctive whiteness on the cephalothorax and the beginning of the abdomen. Like many species of the superfamily Araneoidea, most of them have striped legs specialized for weaving (where their tips point inward, rather than outward as is the case with many wandering spiders). Their contrast of dark brown/black and green/yellow allows warning and repelling of potential predators to which their venom might be ...

Trichonephila Edulis
''Trichonephila edulis'' is a species of large spider of the family Araneidae, formerly placed in the genus ''Nephila''. It is referred to the common name Australian golden orb weaver. It is found in Indonesia from Java eastwards, Papua New Guinea, Australia, northern New Zealand, and New Caledonia. It has a large body size variability, females can reach a body length of up to 40 millimetres, males about 7 mm. The cephalothorax is black with a white pattern on the back, and a yellow underside; the abdomen is grey to brown. The web is about 1 metre in diameter and protected on one or both sides by a strong "barrier" web. ''T. edulis'' breeds from February to May, and produces an average of 380 eggs. According to the phylogeny tree of Nephilidae, ''T. edulis'' is closely related to its congener ''Trichonephila plumipes'' (tiger spider) which is also commonly found in Australia. Name The species was first collected and named by Jacques Labillardiere, in ''Relation du Voy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orb-weaver Spider
Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs. The family has a cosmopolitan distribution, including many well-known large or brightly colored garden spiders. With 3,108 species in 186 genera worldwide, the Araneidae comprise the third-largest family of spiders (behind the Salticidae and Linyphiidae). Araneid webs are constructed in a stereotypical fashion, where a framework of nonsticky silk is built up before the spider adds a final spiral of silk covered in sticky droplets. Orb webs are also produced by members of other spider families. The long-jawed orb weavers (Tetragnathidae) were formerly included in the Araneidae; they are closely related, being part of the superfamily Arane ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Tamerlan Thorell
Tord Tamerlan Teodor Thorell (3 May 1830 – 22 December 1901) was a Sweden, Swedish arachnologist. Thorell studied spiders with Giacomo Doria at the Museo Civico di Storia Naturale de Genoa. He corresponded with other arachnologists, such as Octavius Pickard-Cambridge, Eugène Simon and Thomas Workman (entomologist), Thomas Workman. He described more than 1,000 spider species during his time from the 1850 to 1900. Thorell wrote: ''On European Spiders'' (1869) and ''Synonym of European Spiders'' (1870-73). Taxonomic honors The Orb-weaver spider genus ''Thorellina'' and the jumping spider genus ''Thorelliola'' are named after him, as well as about 30 species of spiders: * ''Araneus thorelli'' (Roewer, 1942) (Myanmar) (Araneidae) * ''Gasteracantha thorelli'' Keyserling, 1864 (Madagascar) (Araneidae) * ''Leviellus thorelli'' (Ausserer, 1871) (Europe) (Araneidae) * ''Mandjelia thorelli'' (Raven, 1990) (Queensland) (Barychelidae) * ''Clubiona thorelli'' Roewer, 1951 (Sumatra) (Clubi ...
