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.
Stegodyphus spiders have a tough carapace with white hairs along the body. Males Stegodyphus spiders have dark borders and narrow white bands along the abdomen, while females have dark longitudinal bands along the abdomen. [1] Spiders of this genus vary from total length, typically between 2.3 and 3.5 mm.
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]
Cyrtophora citricola falls into the family Araneidae because of three characteristics. The male's palpal faces the mesial, or midline of the body.The male spider's palpal has an exoskeleton on their bulbous known as a radix, and the spider has a thin reflective layer of tissue in the posterior set of its eyes called the tapetum.

Desert grass spiders are most active at night in their search for food, but may be seen emerging from their funnel during the daytime if prey steps on the flat part of their webs. [3] A. aperta can tell the difference between more profitable and less profitable prey, with “profit” meaning how much energy they gain from the prey and how ...
Like all Old World tarantulas, spiders in the genus Cyriopagopus lack the urticating hairs found in their New World counterparts, [7] hence use biting as a primary means of both attack and defence. Some Cyriopagopus species are among those reported to have more toxic venom. Although bites may cause severe pain and a range of other effects, no ...
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. [2] As of December 2023, 1,100 species have been identified, with 166 genera. [3] The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas".
