Social spider

The first pic shows the spider lying in its nest and the second pic shows the communal web of the Social spiders. A social spider is a spider species whose individuals form relatively long-lasting aggregations. Whereas most spiders are solitary and even aggressive toward other members of their own species, some hundreds of species in several families show a tendency to live in groups, often referred to as colonies. By building a communal web, it is thought that the spiders approximately maximize total biomass capture per spider. Having a larger web and multiple spiders to work together to subdue prey allows them to prey on larger organisms that would be impossible if they led a solitary existence. The colonies can grow large enough to take down birds and bats as well as very large insects.
