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.
Like other arachnids, spiders are unable to chew their food, so they have a mouth part shaped like a short drinking straw that they use to suck up the liquefied insides of their prey. However, they are able to eat their own silk to recycle proteins needed in the production of new spider webs. [4] Some spiders, such as the dewdrop spiders , even ...

Nursery web spiders (Pisauridae) are a family of araneomorph spiders first described by Eugène Simon in 1890. [1] Females of the family are known for building special nursery webs. When their eggs are about to hatch, a female spider builds a tent-like web, places her egg sac inside, and stands guard outside, hence the family's common name.
Female southern house spiders are rarely seen, as they build radial webs around crevices, for which reason their family (Filistatidae) is called crevice weavers. Females seldom move except to capture prey caught in their webs. Males, on the other hand, typically wander in search of insects and females to mate with, having no particular territory.
Luckily, spiders eat mostly insects -- especially the ones you may also find in your home. But as spiders get bigger, so do their prey, and larger arachnids feast on lizards, birds and small mammals.
Their bite is extremely painful and, but luckily, an antivenin (a.k.a. anti-venom, or an injection given to boost antibodies against a particular poison) now exists. Think you can ID a black widow ...
Cobweb spiders typically live on windows or in dark areas. They eat for a margin of their day and spend hours developing their web; it does not break if it is woven well. Below or in its web, there may be many dead insects, ranging from stinkbugs to other spiders including Lycosidae, to large Scutigera and even wasps. Of the Steatoda, they are ...
