Harvestmen do not have silk glands, so they cannot spin webs they also lack the venom glands that true spiders possess.

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. Learn how to identify the Short-Bodied Cellar Spider, a common household spider with long legs and a small, round body. 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. Perhaps the most common species in our area is the longbodied cellar spider, Pholcus phalangioides. 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. This is a small brown spider (body length around 6 mm), with a short, broad abdomen. Most have oval or rounded abdomens, sometimes described as “peanut shaped.” Females build nonadhesive, unorganized, messy-looking cobwebs, usually in corners or crevices. Physocyclus globosus, sometimes known as the short-bodied cellar spider is a species of spider belonging to the family Pholcidae.This is a cosmopolitan species, found in caves and buildings throughout the warmer parts of the world. If you are bitten by a cellar spider, seek medical attention immediately. It can cause redness and swelling around the bite site.

The cellar spider’s bite generally causes only minor symptoms, but in some cases, it can lead to more serious reactions. Some species have darkened joints on their legs, giving them a “knobby-kneed” look. The vast majority of cellar spider bites cause only minor symptoms that are mild and short-lived. This movement turns them into a blur, rendering them practically invisible to potential predators. These are small brown spiders with a broad abdomen and long legs.

This is a cosmopolitan species, found in caves and buildings throughout the warmer parts of the world. The Short-bodied Cellar Spider (Physocyclus globosus) belongs to the Pholcidae family and is often found in buildings and caves in warmer climates. 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. Physocyclus globosus, sometimes known as the short-bodied cellar spider is a species of spider belonging to the family Pholcidae. The tarsi (“feet”) are flexible, adding to the wispy impression they give. Cellar spiders are inconspicuous, harmless, fragile spiders with extremely long, thin legs.
