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.
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.
Wolf spiders resemble nursery web spiders (family Pisauridae), but wolf spiders carry their egg sacs by attaching them to their spinnerets, while the Pisauridae carry their egg sacs with their chelicerae and pedipalps. Two of the wolf spider's eight eyes are large and prominent; this distinguishes them from nursery web spiders, whose eyes are ...
Hogna carolinensis is commonly known as the Carolina wolf spider. Historically, it was known as Lycosa carolinensis, but refinement in taxonomy in the later half of the 20th century led to L. carolinensis, among many other spiders, being reclassified to the current genus, Hogna.
Kauaʻi cave wolf spiders only produce 15-30 eggs per clutch, whereas other terrestrial wolf spiders may have 100 to 300. Female Kauaʻi cave wolf spiders carry their egg sacs on their backs until their spiderlings hatch in 30 to 50 days. Upon hatching, the large spiderlings will be carried on the back of the mother for several days. Kauaʻi ...
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.
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. [3] Some spiders, such as the dewdrop spiders , even ...
Wolf spider. What they look like: With over 200 species of wolf spiders crawling around, it’s no wonder that they range in size and appearance. “The largest species can be up to an inch and a ...
