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.
Tarantulas use their pedipalps to help groom themselves, especially after a meal. During reproduction, males use their pedipalps as external reproductive organs. They develop emboli and palpal bulbs on the ends of each palp. [4] Tarantulas have 8 legs and each foot ends with a cluster of bristles called scopulae and a pair of tarsal claws ...
Female P. murinus can grow to 4–6 inches (10–15 cm) in size (measured from the tip of the front left leg, to the tip of the rear right leg), while males typically range from 3–4 inches (7.5–10 cm). The spider's abdomen, carapace, and legs have the same basic coloration, though the legs typically have brightly colored rings.
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.
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]
Tarantulas normally hunt by staying in their burrows and waiting for their prey to come to them, according to a Texas A&M field guide. Their prey includes crickets, beetles, grasshoppers, cicadas ...
Receptive females will allow a male to mate, usually during the rainy season, resulting in the making of an egg sac and the laying of 300 to 500 eggs several weeks later. The egg sac is incubated for about seven to eight weeks at 24 to 27 °C (75 to 81 °F), after which pale-colored young emerge and cluster together.
During the first instar period, the spiders are inactive and lay on their backs stretching their limbs, then moulting after five weeks. The second instar spiders are more active and begin spinning webs and feeding. [7] [2] [18] The spiderling tends to grow to a length of 12mm by the end of the first year. After 2–3 years, the spider reaches ...
