Cyrtophora Lahirii
''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 long. Some members, including ''Cyrtophora cicatrosa'', exhibit the ability to change colour rapidly. A kleptoparasitic spider (''Argyrodes fissifrons ''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. Description The female is larger than the male, at about 12mm in length. The abdomen i ...'') was found to live in a mutualistic relationships with ''Cyrtophora'' species. Some of the species are considered socia ...

Cyrtophora Moluccensis
''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. The abdomen is high and the anterior end overhangs the cephalothorax. It can be distinguished from similar species by the two tubercles on its abdomen, its elaborate pattern, and, in females, the shape of the median septum of the epigyne. In males, the embolus of the pedipalp is enclosed within the conductor. Females and immature spiders are yellow to green in color. Webs built by ''Cyrtophora'' species are different from typical webs built by orb-weavers. The orb web is built horizontally with a finely meshed dome or bowl shape, hence the name "dome-web spider". The non-sticky spiral is left intact and webs are without a sticky spiral. A 1980 study suggests that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
