Gasteracantha Mammosa
''Gasteracantha cancriformis'' (spinybacked orbweaver) is a species of orb-weaver spider (family Araneidae). It is widely distributed in the New World. The genus name ''Gasteracantha'' derives from the Greek words (', "belly") and (', "thorn"), while the specific epithet ''cancriformis'' derives from the Latin words ' (" crab") and ' ("shape, form, appearance"). Description Females are long and wide. The six abdominal spine-like projections on the abdomen are characteristic. The carapace, legs, and underside are black with white spots under the abdomen. Variations occur in the colour of the upperside of the abdomen - a white or yellow colour with both featuring black spots. A white upper side can have either red or black spines while a yellow upperbside can only have black ones. Like with many other spiders, males are much smaller (2 to 3 mm long) and longer than wide. All morphs have six abdominal spines. They are similar to the females in colour, but have a gray a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metepeira Incrassata
''Metepeira incrassata'', also known as the colonial orb-weaving spider, belongs to the spider family Araneidae and genus Metepeira. They are most famous for their social organization and group living behavior. They are generally found in tropical rainforest and agricultural sites in Mexico, and their habitats tend to be highly productive (high generation rate of biomass). Their group sizes are relatively larger than other colonial spiders, typically ranging from hundreds to thousands of individuals. 99% of the females are observed to participate in colonial living, generally with at least two other individuals. Because most ''M. incrassata'' females are communal, the colonies are often dominated by larger males. There is minimal sexual dimorphism observed in ''M. incrassata''. Unlike other orb-weaver spiders, ''M. incrassata'' builds a colonial web by connecting each spider's individual webs together through semi-permanent framelines. These colonial webs of ''M. incrassata'' are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasteracantha
''Gasteracantha'' is a genus of orb-weaver spiders first named by Carl Jakob Sundevall in 1833. Species of the genus are known as spiny-backed orb-weavers, spiny orb-weavers, or spiny spiders. The females of most species are brightly colored with six prominent spines on their broad, hardened, shell-like abdomens. The name ''Gasteracantha'' is derived from the Greek (), meaning "belly, abdomen", and (), meaning "thorn, spine". Spiny-backed orb-weavers are sometimes colloquially called "crab spiders" because of their shape, but they are not closely related to the true crab spiders. Other colloquial names for certain species include thorn spider, star spider, kite spider, or jewel spider. Members of the genus exhibit strong sexual dimorphism. Females are several times larger than males, which lack prominent spines or bright colors. ''Gasteracantha'' species are distributed worldwide in tropical and subtropical climates. The genus is most diverse in tropical Asia, from India t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philoponella Vicina
''Philoponella vicina'' is a species of spider that does not use venom (characteristic of Uloboridae), but instead wraps its prey in hundreds of metres of spider silk to crush it to death. The spider then goes on to regurgitate digestive fluid into the shroud, then consuming the pre-digested liquid. Stabilimenta occur in more than half of constructed orbs, most commonly with two lines pointing up and down from the spider. If only one radius is constructed, it is mostly constructed above the spider. Some spiders build resting webs that are not used for prey capture. These also sometimes feature stabilimenta, suggesting that prey capture plays no role in its construction. When disturbed, the spider flees up one of the stabilimentum lines.

Austracantha Minax
''Austracantha'' is a genus of spider with a single species, ''Austracantha minax'', commonly known as the jewel spider or the Christmas spider. It is a member of the family Araneidae (the orb-weavers) and is endemic to Australia. They are relatively small spiders, reaching a maximum total body length of only around for females, and for males. Their abdomen has six distinctive projections ("spines") that makes them easy to identify. They are predominantly a shiny black, with variable white, yellow, and orange patterns. Melanistic forms also occur during autumn. They are facultatively gregarious, and can be found in large aggregations of overlapping orb webs. They feed on small flying insects that get entangled in their webs. They are harmless to humans, though the webs can be a nuisance for bushwalkers. They are most abundant during the summer months. Taxonomy and nomenclature ''Austracantha minax'' is most commonly known as "jewel spiders" due to their body colouration. ...

Thelacantha Brevispina
''Thelacantha'' (Asian spinybacked orbweaver) is a genus of orb-weaver spiders containing the single species, ''Thelacantha brevispina''. It was first described by A. W. M. van Hasselt in 1882, and has been found in Australia, Madagascar, and across southern Asia from India to Philippines, including Japan. It has also been introduced into Hawaii. ''T. brevispina'' is closely related those in the genus ''Gasteracantha'', and was briefly synonymized with it in 1859, but revalidated in 1974. Saito described three other ''Thelacantha'' species in 1933, which were later synonymized with ''T. brevispina''. Description Females grow to about long, while males reach a size of . Females have six abdominal spines ending in distinct sharp points. Most have two large white spots on the upper surface of their abdomens, which are otherwise mottled with black, brown, and white patterns.

Ecuador
Ecuador ( ; ; Quechua: ''Ikwayur''; Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechua: ''Ikwadur Ripuwlika''; Shuar: ''Ekuatur Nunka''), is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as its own sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
