Unlike other species of spiders that take down their webs. As the name would suggest, cellar spiders often make their homes in the damp and dark corners of basements, crawl spaces, sheds, and warehouses.

Harvestmen do not have silk glands, so they cannot spin webs they also lack the venom glands that true spiders possess. The long-bodied cellar spiders have legs that can be up to two inches long, while those of the short-bodied spiders can be about ½ inch. Among the obvious structural differences are harvestmen’s having one apparently unified (usually egg-shaped) body, while true spiders have clearly separate head and abdomen regions. Similar species: Though they also have long, thin legs and are also often called daddy longlegs, harvestmen (in order Opiliones) are quite different and unrelated. To distinguish it from other cellar spiders may require close examination of palps, “face” structure, carapace markings, and eye groupings. As their name implies, cellar spiders are found in dark and damp places like cellars and basements. Pholcid spiders (Araneae: Pholcidae) are an example of disconnect between public perception, and scientific understanding. Perhaps the most common species in our area is the longbodied cellar spider, Pholcus phalangioides. There are both long-bodied as well as short-bodied cellar spiders. Many common spiders in this family have 8 eyes arranged into three groups: 2 in the center of the face, and a cluster of 3 on each side of the central pair.

Unlike many species of spider, these two kinds don’t attach their egg sacs to webs but carry them in their mouthparts instead. On the other hand, a short-bodied female spider can create 1027 eggs per case. This is the only spider species described by the Swiss entomologist Johann Kaspar Füssli, who first recorded it in 1775. Most have oval or rounded abdomens, sometimes described as “peanut shaped.” Females build nonadhesive, unorganized, messy-looking cobwebs, usually in corners or crevices. The Long Bodied Cellar Spider, Pholcus phalangioides, is also commonly called a Daddy Long Legs or Cobweb Spider. Females of long-bodied cellar spiders only produce three egg sacs throughout their lifespan, each containing 13 to 60 eggs. Pholcus phalangioides, commonly known as daddy long-legs spider or long-bodied cellar spider, is a spider of the family Pholcidae.It is also known as the skull spider, since its cephalothorax resembles a human skull. Some species have darkened joints on their legs, giving them a “knobby-kneed” look. This movement turns them into a blur, rendering them practically invisible to potential predators. Other characteristics add to their camouflage: Their gray, tan, or whitish color, small body size, and remarkable habit of “vibrating” or bouncing rapidly in their webs when alarmed. Long-bodied cellar spider (Pholcus phalangioides). The tarsi (“feet”) are flexible, adding to the wispy impression they give. Cellar spiders are inconspicuous, harmless, fragile spiders with extremely long, thin legs.
