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.
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.
A unique behavior of this tarantula is that it is communal, to the point that mother spiders care for the young, even attacking potential predators if they get too close to her egg sac. In captivity, multiple males and females of different ages may live together without attacking one another, provided that they have enough food and proper care.
Spiders are compelled to retrieve snagged prey upon vibratory cues. [11] The Stegodyphus dumicola have been found to follow a “shy” and a “bold” personality, where shy spiders are latent and do not respond to prey capture stimuli, and bold spiders are active and seek to forage. Smaller spiders tend to have a bold personality.
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]
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.
At Bugs Café, also in Siem Reap, there’s a similar, albeit more graphic, iteration of insect-driven dining, where a platter of insect skewers, scorpion salad, silkworm croquettes, stir-fried ...
The spiderlings hatch in this retreat, being released from their cocoon by their mother and then protected by her for another two weeks. Web-building behavior uses up time and energy, but provides an advantage in the ability to catch prey. Fixing and constructing webs occurs only at night, but prey capture can occur during the day or at night.
