Cyrtophora unicolor is a species of spider of the family Araneidae. [1] It is known as the red tent spider. [3]
The species shows sexual dimorphism, where the male is small and with faded colors, whereas the female is much larger and with a brilliant red color. [3] The female is 17-20mm in length. [4]
The red tent spider builds a large three-dimensional web in vegetation, which is a common feature of members of the genus. [5]
It is found in numerous Asian countries, including Singapore, China, Southern Taiwan, Japan, Philippines, Papua New Guinea, Indonesia, Christmas Island, Sri Lanka, Thailand, Myanmar, and north-eastern India. [3]
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.
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 and is endemic to Australia. They are relatively small spiders, reaching a maximum total body length of only around 12 mm (0.47 in) for females, and 5 mm (0.20 in) 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.
Micrathena gracilis is a spider in the family Araneidae (orb-weavers), commonly known as the spined micrathena or castleback orbweaver. This spider spins a moderately large and very tightly coiled web. The spiders themselves are small and can be found to be anywhere from 4.2 mm to 10.8 mm long. Its venom is harmless to humans. M. gracilis is unique in appearance due to its large spiky abdomen and black and white bodies. Certain spiders of this species can also display a yellow color on the sides of their bodies. These spiders can be seen most active during the end of the summer and beginning of fall. M. gracilis is diurnal and are rarely ever seen active at night.
Argiope aetherea is a common, large orb-web spider. Like other species of Argiope, it is commonly known as the St Andrew's Cross spider, due to the characteristic cross-shaped web decorations female spiders often include in their webs. A. aetherea is similar in appearance to A. keyserlingi, however female A. aetherea are generally larger than A. keyserlingi. Like most orb-web spiders, A. aetherea shows considerable sexual size dimorphism, with females being many times larger than males.
Nuctenea umbratica, the walnut orb-weaver spider, is a species of spider in the family Araneidae.
Araniella cucurbitina, sometimes called the "cucumber green spider", is a spider of the family Araneidae. Araniella cucurbitina is found across Europe, Western Asia, Central Asia and Japan. The cucurbitina in the name comes from the word cucurbit which is a family of plants including cucumbers.
Cyrtophora, the tent-web spiders, is a genus of orb-weaver spiders first described by Eugène Simon in 1895. Although they are in the "orb weaver" family, they do not build orb webs. Their tent-like, highly complex non-sticky web is sometimes considered a precursor of the simplified orb web. These webs are aligned horizontally, with a network of supporting threads above them. These spiders often live in colonies. Females have a body length of mostly about 10 millimetres (0.39 in) long. Some members, including Cyrtophora cicatrosa, exhibit the ability to change colour rapidly.
Argyrodes argentatus is a kleptoparasitic spider.
Gasteracantha cancriformis is a species of orb-weaver spider. It is widely distributed in the New World.
Araneus marmoreus, commonly called the marbled orbweaver, is a species of spider belonging to the family Araneidae. It is sometimes also called the pumpkin spider from the resemblance of the female's inflated abdomen to an orange pumpkin. It has a Holarctic distribution.
Cyrtophora citricola, also known as the tropical tent-web spider, is an orb-weaver spider in the family Araneidae. It is found in Asia, Africa, Australia, Costa Rica, Hispaniola, Colombia, and Southern Europe and in 2000, it was discovered in Florida. C. citricola differs from many of its close relatives due its ability to live in a wide variety of environments. In North America and South America, the spider has caused extensive damage to agricultural operations.
Darwin's bark spider is an orb-weaver spider that produces the largest known orb webs, ranging from 900 to 28,000 square centimetres, with bridge lines spanning up to 25 metres (82 ft). The spider was discovered in Madagascar in the Andasibe-Mantadia National Park in 2009. Its silk is the toughest biological material ever studied. Its tensile strength is 1.6 GPa. The species was named in honour of the naturalist Charles Darwin on November 24, 2009—precisely 150 years after the publication of The Origin of Species.
Cyrtophora exanthematica are tent spiders common in tropical Asia and Australia. They are commonly known as double-tailed tent spiders because of the pair of blunt projections at the end of their abdomens. They are harmless to humans.
Cyrtophorinae is a subfamily of spiders in the orb-weaver spider family. Unlike other orb-weavers, spiders belonging to Cyrtophorinae build horizontal, finely meshed platforms within a tangle of irregular webs. The usually dome-shaped platform is a non-sticky orb web.
Cyrtophora parangexanthematica is a species of tent spider found in the Philippines. Its scientific name comes from its close resemblance to double-tailed tent spiders. It was described from a single female specimen collected in 1995.
Araneus mitificus, commonly known as the kidney garden spider or pale orb weaver is a species of orb-weaver spider found in South, East, and Southeast Asia.
Cyrtophora moluccensis is a tent-web spider in the orb-weaver family. It is commonly known as the tent spider or dome-web spider, and is native to India, Japan, Indonesia, Papua New Guinea, Australia, Fiji, and Tonga. It is often found in disturbed or open habitats from coasts to forest and mountainous interiors.
Argyrodes fissifrons, the split-faced silver spider, is a species of spider of the genus Argyrodes. It is found from Sri Lanka to China and Australia.
Allocyclosa is a genus of orb weaver spiders that contains only one species, Allocyclosa bifurca. It was first described in 1887 by McCook under the name Cyrtophora bifurca, and was transferred to its own genus in 1999. It is the only Cyclosa species north of Mexico to have a forked tail, hence the name bifurca, Latin for "two-forked". The forked abdomen, bearing two humps shaped like the letter M, is a defining feature in both males and females, though it is similar to features present in certain Cyrtophora species. Both sexes are a transparent green color, though only females have an area of red on their underside between the epigynum and the spinnerets. Females are nearly thirty percent larger than males, ranging from five to nine millimeters, while males range from two to three millimeters. Males are very uncommon. In a 1977 study by Levi, only two of the nearly 350 specimens that were positively identified as Cyrtophora bifurca were males. This is a very odd distribution, and it has been posed that females of the species, which have less prominent genitalia relative to other members of the orb-weaver family, may be parthenogenic, or able to reproduce without the help of males. Like other members of Araneidae, these spiders create orb webs, six to eight inches in diameter, but apply a unique form of protective mimicry. Females sit in the middle of a vertical row of web decoration, with egg sacs above and wrapped prey below. Because they all have a similar color and shape, it is difficult to discern between the egg sacs, the wrapped prey, and the spider itself.
Cyrtophora cicatrosa, commonly known as the garden tent-web spider or dome spider, is a common species of orb-weavers found in many parts of Asia. It is common in gardens and has a very dense, thick, three dimensional and strong tent-like web.
