What Are Cellar Spiders?Ĭellar spiders belong to a scientific family known as Pholcidae. There’s so much to learn about them, and in this article, we’ll discuss everything you need to know about cellar spiders. If so, you’re in the right place.Ĭellar spiders get their name from their characteristic feature of being found in cellars, damp places, crawl spaces, and basements. Have you heard about cellar spiders? Maybe you’ve noticed some spiders around your house and are wondering if they’re cellar spiders. ^ "Ogre-faced spiders have great hearing-without ears".^ "Ogre-Faced Spiders: These Spiders Can Hear – Even Though They Have No Ears".Proceedings of the Royal Society of London.

To aid further in netting prey, the spider places white fecal spots on the surface below the net and uses them for aiming. This is despite the fact that they lack a reflective layer ( tapetum lucidum) instead, each night, a large area of light-sensitive membrane is manufactured within the eyes, and destroyed at dawn, with the membrane being converted into vesicles which are then lysed in the inter-rhabdoneral cytoplasm. These eyes have a wide field of view and are able to gather available light more efficiently than the eyes of cats and owls, and are 2000 times more sensitive to light than human photoreceptors. The two posterior median eyes are enlarged and forward-facing. Passing prey is then captured by dropping the "net" over it. This is then detached from its supporting threads and held horizontally above the ground by the spider's long front two pairs of legs while the spider hangs almost vertically. They first spin a small upright rectangular cribellate web. Spiders in the genus Deinopis catch their prey in an unusual fashion. The spelling " Dinopis" is also found, but is regarded as an "unjustified emendation". The name is derived from the Greek δεινός ( deinos), meaning "fearful", and opis, meaning "appearance", referring to their ogre-like faces. They catch their prey using a specially spun "net". Its distribution is widely tropical and subtropical. Deinopis, also known as net-casting spiders, gladiator spiders and ogre-faced spiders, is a genus of net-casting spiders that was first described by W.
