Stegodyphus dumicola, commonly known as the African social spider, is a species of spider of the family Eresidae, or the velvet spider family. It is native to Central and southern Africa . This spider is one of three Stegodyphus spiders that lives a social lifestyle ( S. lineatus , S. mimosarum , and S. dumicola ).
Once the spider is ready to lay eggs, the C. brunnea larva will quickly move into the sticky fluid the spider is using to construct the egg sac and thus the larva becomes trapped within the sac. Inside, the larva will use its specially adapted sucking tube (made from its maxilla and mandibles) to feed off the spider eggs within the sac. [3]
In addition to preserving spiders' anatomy in very fine detail, pieces of amber show spiders mating, killing prey, producing silk and possibly caring for their young. In a few cases, amber has preserved spiders' egg sacs and webs, occasionally with prey attached; [93] the oldest fossil web found so far is 100 million years old. [94]
Zygiella x-notata has an annual life cycle. Female spiders lay eggs in autumn, predominantly during the months of September and October. While males die soon after mating, surviving females protect the egg sacs over winter from Hymenopteran parasites. Egg sacs hatch in spring, and spiderlings subsequently disperse.
Hot, dry conditions are often associated with population build-up of spider mites. Under optimal conditions (approximately 27 °C), the two-spotted spider mite can hatch in as little as 3 days, and become sexually mature in as little as 5 days. One female can lay up to 20 eggs per day and can live for 2 to 4 weeks, laying hundreds of eggs.
The period of time between mating, egg-laying and emergence of spiderlings can vary, and is temperature dependent. [10] They are able to build several egg sacs within one season, [7] and one study found that one female spider produced four egg sacs within four months. S. nobilis can produce large amounts of offspring for a long period after ...
Female in retreat with egg sac. The labyrinth spider is active, with its webs visible, from March through October. During the rainy season, the female mates and lays eggs. [2] The female usually produces 5 or 6 egg sacs with an average of 55 eggs each. [1]
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.
