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.
When these spiders were on an adequate diet, regardless of solitary or communal, they produced an average of 23 eggs per egg case, compared to those on a poor diet, who only produced an average of 10 eggs per egg case. The higher feeding rate per hour within communal groups and increase in eggs produced when on a sufficient diet explains why ...
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.
The female produces an egg sac around 9 millimetres (3 ⁄ 8 in) long and fairly flat and elongate in shape. The outer covering is grey or brown of a rough texture. The egg sacs are suspended in the communal web, tapering at the ends and having several lateral points. It may be mistaken for vegetative debris or digested food.
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.
What do tarantulas eat? 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 ...
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.
Spiders could, theoretically, eat every single human on earth within one year. It gets worse. Those humans consume about 400 million tons of meat and fish each year, so ultimately, the tiny ...
