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 have been used in studies which indicate that invertebrates may experience pain. Under natural conditions, orb-weaving spiders (Argiope spp.) undergo autotomy (self-amputation) if they are stung in a leg by wasps or bees. Under experimental conditions, when spiders were injected in the leg with bee or wasp venom, they shed this appendage.
Jumping spider diets consist of small insects such as grasshoppers, moths, flies, or other spiders. They can eat almost anything that their chelicerae can hold. Other prey includes fruit flies, bees, wasps, crickets, worms, butterflies, or leafhoppers. [6] [7] [10]
A spider could do this only a few ways, like using its silk to float and land in a sleeping person's mouth. But Maggie Hardy, biochemist at the University of Queensland, said, "You'd have to be ...
Although they miss on about 50% of strikes, they catch about the same weight of insects per night as web-weaving spiders of similar size. The spiders eat the bolas if they have not made a kill in about 30 minutes, rest for a while, and then make new bolas. [66] [67] Juveniles and adult males are much smaller and do not make bolas.

This seasonality of reproduction is largely due to the male spiders, who spend the winter months molting to adulthood, while female spiders are present year-round. This is evidenced by the reduction in eggs found during winter months. Egg clutches are enclosed in a 5 mm thick cocoon, hidden about 12 cm deep in the burrow.
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.
