A collective web of Agelena consociata in Uganda.. 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.
Desert Spider, Stegodyphus lineatus, one of the best-described species that participates in matriphagy Matriphagy is the consumption of the mother by her offspring. [1] [2] The behavior generally takes place within the first few weeks of life and has been documented in some species of insects, nematode worms, pseudoscorpions, and other arachnids as well as in caecilian amphibians.
Females reach six inches in diagonal leg span on average while males can reach 5 inches. Males are sexually dimorphic, appearing to have much thinner legs as well losing most of their coloration, it can be hard to distinguish them from Psalmopoeus cambridgei mature males. Females can live up to 12 years while males only live to about 4 years.
Spiders have been observed to grab onto the prey's leg and move away into an area when none of the spiders can see it eating first. Otherwise, all the individuals in the nest eat together, breaking away different portions to jointly divide the meal. Communal feeding occurs even with spiders who may not have taken part in the prey capture.
Sacrificial mothers: Offspring of the species Stegodyphus lineatus eat their mother. Females of Segestria florentina sometimes die while guarding her eggs and the hatched spiders later eat her. Non-reproductive cannibalism: Some spiders, such as Pholcus phalangioides, will prey on their own kind when food is scarce. [18]

A male Eresus sandaliatus. Sexual selection in spiders shows how sexual selection explains the evolution of phenotypic traits in spiders.Male spiders have many complex courtship rituals and have to avoid being eaten by the females, with the males of most species surviving only a few matings and consequently having short life-spans.
Like other arachnids, spiders are unable to chew their food, so they have a mouth part shaped like a short drinking straw that they use to suck up the liquefied insides of their prey. However, they are able to eat their own silk to recycle proteins needed in the production of new spider webs. [4] Some spiders, such as the dewdrop spiders , even ...
