Cyrtophora moluccensis (Tent Spider) - Sikkim Spider

Scientific classification

Kingdom:  Animalia
Phylum:     Arthropoda
Class:         Arachnida
Order:       Araneae
Suborder: Araneomorphae
Family:     Araneidae
Genus:      Cyrtophora
Species:    C. moluccensis

Binomial name: Cyrtophora moluccensis (Doleschall, 1857)

Other Names:  Tent Spider or Dome-Web Spider

Special feature:  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.

Cyrtophora, the tent-web spiders, although technically orb-web spiders (family Araneidae), 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 mm. (Source: Wikipedia)
