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. The male spiders do not transfer the sperms directly. An interesting fact about daddy long-legs spiders is that, they can breed throughout the year. 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. The male cellar spiders reach the age of reproduction in one year and usually die after copulating, while the female can live for about 3 years. To distinguish it from other cellar spiders may require close examination of palps, “face” structure, carapace markings, and eye groupings. Along with this, daddy long legs do not produce webs, so if you’re seeing them in and around webs you’re. Cellar spiders have long peanut shaped bodies, while daddy long legs typically have much rounder and fatter bodies. Perhaps the most common species in our area is the longbodied cellar spider, Pholcus phalangioides. When trying to identify if you’re dealing with a cellar spider or a daddy long leg, you should focus on the body. 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. Sometimes called the Daddy Long-legs Spider it is relatively easy to identify due to the very long legs and cylindrical body. While cellar spiders might be considered an eyesore, they are harmless. The picture shows a close-up view of the cellar spider’s two body parts. However, their two body parts puts them in the spider category rather than the Opilione category of another daddy long legs species. Some species have darkened joints on their legs, giving them a “knobby-kneed” look. Their long legs makes the nick-name daddy long legs appropriate. 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. It’s known for having extremely long legs and a relatively small body, which should be noted immediately. The brown recluse has a much thicker body and head, while the cellar spider’s body is much different. The tarsi (“feet”) are flexible, adding to the wispy impression they give. The first and most obvious difference is the body size of the animal. Cellar spiders are inconspicuous, harmless, fragile spiders with extremely long, thin legs.
