Long bodied cellar spider facts'4/5/2024 ![]() It is this competition that helps keep Tegenaria populations in check, which may be advantageous to humans who live in regions with dense hobo spider populations. Pholcids are natural predators of the Tegenaria species, and are known to attack and eat redback spiders, huntsman spiders and house spiders. In some cases the spider vibrates the web of other spiders, mimicking the struggle of trapped prey to lure the host of the web closer. DietĬertain species of these seemingly benign spiders invade webs of other spiders and eat the host, the eggs, or the prey. The prey may be eaten immediately or stored for later. The spider quickly envelops its prey with silk and then inflicts the fatal bite. The web has no adhesive properties but the irregular structure traps insects, making escape difficult. However, Pholcids are also quite commonly found in warm, dry places, such as household windows and attics. These webs are constructed in dark and damp recesses, such as: caves, under rocks and loose bark, abandoned mammal burrows, and undisturbed areas in buildings, such as cellars (hence the common name "cellar spider"). They hang inverted in messy, irregular, tangled webs. Pholcids are found in every continent in the world except Antarctica where it is too cold for them to survive. It can be clear, clear brown, brown or gray. The cellar spiders torso is thin and doesn't have a fixed colour. The shape of the Pholcus and Smeringopus's body resembles that of a peanut. Pholcids are gray to brown with banding or chevron markings. Spermophora has a small globose abdomen and its eyes are arranged in two groups of three and no median eyes. Eight and six eyes both occur in this family. Pholcus and Smeringopus have cylindrical abdomens and the eyes are arranged in two lateral groups of three and two smaller median contiguous eyes. Pholcids are fragile arachnids, the body being 2–10 mm in length with legs which may be up to 50 mm long. Spiderlings are transparent with short legs and change their skin about 5 or 6 times as they grow.įemales have a body length of about 9mm, males are slightly smaller.Ĭrossopriza lyoni and Physocyclus globosis are spiders with a very similar appearance. The female holds 20 to 30 eggs in her jaws. Because they originally came from the tropics, these spiders do not seem to be aware of seasonal changes and breed at any time of the year. When food is scarce, they will prey on their own kind. They can easily catch and eat hairy house spiders, mosquitoes, and other insects. Because it is often found on the ceilings of rooms, caves or cellars, it is also called cellar spider. This is probably to blur the vision of a predator. phalangioides has the habit of shaking the web violently when disturbed. ![]() It is often confused with the daddy long-legs, a member of the Opiliones, which are not true (real) spiders. Its legs are about 5 or 6 times the length of its body. The Daddy-Long-Legs Spider ( Pholcus phalangioides) is a spider of the family Pholcidae.
