Harvestmen do not have silk glands, so they cannot spin webs they also lack the venom glands that true spiders possess.Close-up of Cellar Spider ( Pholcus phalangioides) Cellar spiders: (A.K.A. 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. 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. Most have oval or rounded abdomens, sometimes described as “peanut shaped.” Females build nonadhesive, unorganized, messy-looking cobwebs, usually in corners or crevices.
