Cellar spiders are easily identified by their extraordinarily long and thin legs which can be up to two inches long. The legs are attached to an elongate and thin body.
They are usually yellowish brown in color.
Cellar spiders like dark, damp areas, such as crawl spaces, basements, and sheds but can also be found around doorways and in garages. Cellar spiders are often referred to as Daddy Long-Legs due to their very long, thin legs. The true Daddy Long-Legs, however, is another animal entirely, called the Harvestman. They create messy webs, which gather dust and floating debris, as well as the remains of the insects the spiders have fed on. Cellar spiders hang upside down on their webs, and when disturbed, they will shake and bounce the web noticeably, or drop off the web and run to hide.
Like all spiders, cellar spiders are predators and carnivores. They will eat just about any kind of insect or bug including moths, mosquitoes, flies, beetles, and other spiders like the black widow and brown recluse. When an insect walks into its web, the cellar spider wraps it up in spider silk and sucks it dry. When the cellar spider is finished, it cuts the insect loose, letting it fall to the ground creating a pile of dead, dry, bug bodies underneath its web.
Cellars spiders prefer to live in secret places and like to live close to their mate. In fact, male and female cellar spiders will often live next door to each other. The female creates an egg mass of about a dozen eggs, and holds it in her jaws until the eggs hatch. The babies hatch after several weeks.
Once a cellar spiderís web gets too old, the spider spins a new web that is attached to the old web. Over time, this creates significant amounts of cobwebs.
