![]() ![]() Can also catch and eat other large spiders that walk into their web, including things like the “ hobo spider,” the “ giant house spider,” and even large “ wolf spiders.” May invade the web of other spiders and eat them, including members of their own species.Eggs are usually visible through the translucent abdominal cuticle of the gravid (pregnant) females.Front legs on an adult can be up to 50 mm (~2″) in length, sometimes more. They are grayish-brown with bands of white and black at the joints. Legs are very, very long and thin delicate-looking. ![]() Pholcus phalangioides has been primarily sighted during the month of March. Pholcus phalangioides has also been sighted in the following states: Alabama, Arkansas, California, Louisiana, Maine, Maryland, Massachusetts, Missouri, New Hampshire, New York, North Carolina, Ohio, Oregon, Pennsylvania, Texas, Washington, Wisconsin. Pholcus phalangioides (Long-bodied Cellar Spider) has been sighted in the following countries: Canada, South Africa, Spain, United Kingdom, United States. Environment: Pholcus phalangioides has been sighted 6 times outdoors, and 32 times indoors.Web: 39% of the time, Pholcus phalangioides spiders are sighted in a spider web (Sample size: 38).The detailed statistics below may not utilize the complete dataset of 38 sightings because of certain Pholcus phalangioides sightings reporting incomplete data. There have been 38 confirmed sightings of Pholcus phalangioides (Long-bodied Cellar Spider), with the most recent sighting submitted on Octoby Spider ID member erniemas. ^ "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.
