LONG BODIED CELLAR SPIDER PATCH
Pholcus phalangioides is pale yellow-brown except for a large gray patch in the center of the cephalothorax. Pholcus phalangioides hangs upside down on the web it makes. Their webs are normally oriented horizontally. They make their webs large, loose, and flat, but they can make them in irregular shapes to fit into surrounding objects. People most often associate these spiders with living on ceilings and in corners in homes. Some places one might encounter this spider are in basements, under stones, under ledges, and in caves. Pholcus phalangiodes can be found in undisturbed, low light locations. It is a common cellar spider throughout the United States. Kindle Edition.Pholcus phalangioides is found throughout the world.
Darwin Comes to Town: How the Urban Jungle Drives Evolution (p. "He discovered that the spiders living in different rooms within one building jointly form a single gene pool, but that each building is a separate gene pool: the spiders move chambers, but rarely move house." * In Darwin Comes to Town Martin Schäfer of the University of Bonn studied the cellar spiders (Pholcus phalangioides)in buildings in five European cities. Recent studies have shown that this species is wide spread in Europe and North America but can have differences in DNA is small "islands" such as apartment buildings. As we see an occasional brown recluse in the nooks and crannies, letting these leggy creatures patrol the house is a small price to pay. On the other hand, they are considered beneficial as they are predators of many venomous spiders that are threats to us. Long-bodied spiders have very weak venom and are barely able to pierce human skin, with only a temporary discomfort. When they perceive a threat they start vibrating on their web, making them harder to see, thus the "vibrating spider" name. Their webs are irregular, messy but very small, tending to cling to a wall or other horizontal surface. Mother and babies - Luis Fernández García via Wikipedia The young will molt six times before they reach maturity Round raised eyes clustered on both sides of the head as well asįemale with egg case - Olei CC- WikimediaĪ female produces 20-30 eggs which she will patiently carry around in her pedipalps until the young hatch. Thorax they are also commonly called a "skull spider." Another defining characteristic of various spider species is the Skull shaped head with two sets of three round eyes tightly clustered together - REK In their original lands they reproduce annually in the warm season while in our house it is always the season to reproduce and life is good. They do not tolerate cold but have found their niche in warm human habitats. They originated in the sub-tropics but are now found on every continent, probably traveling along with the commerce of humans. Both have eight legs typical of the Arachnids. Long-bodied spiders have three distinct body parts (head, thorax and abdomen) while the Opiliones (harvestmen) have the head and thorax fused into one small part frequently making their bodies appear oval. Crane flies have 6 legs like all insects and wings typical of all the Diptera (true flies). This common name is also applied to both harvestmen of the Opilione class and to crane flies which are sometimes mistaken for giant mosquitoes. Their "daddy long-legs" name is appropriate but can be confusing. "Daddy Longlegs" Crane Fly- Six legs of an insect - REK Their bodies are 5-8 mm long, (less than 1/3") and their leg are 8 times longer. They have a number of common names including daddy long-legs spider, granddaddy long-legs spider, carpenter spider, and vibrating spider. This is the Long-bodied Cellar Spider, Pholcus phalangioides, the most common of the Pholcidaeor cellar spiders. For the most part they just hang on a wall or slowly explore the tile floor, looking for tiny pests that we don't even know exist. After all they spend the rest of their lives sequestered in dark, damp places asking for nothing and bothering no one, unless it is a house guest too polite to mention them. After years of watching these leggy spiders crawl all over the bathroom in our creek house, I thought it was time to give them their day in the sun.
