They sometimes hunt around the edges of the webs of female spiders of other species. Many cellar spiders also raid the webs of other spiders, eating their prey and the spiders themselves. When a passing insect bumps into it, they come running out and grab it and bite it, then wrap it in silk. They use their web as a kind of prey-detection system. They spin a large loose, three-dimensional web (not flat like orbweavers) that is not sticky. They eat insects, spiders, and other small invertebrates. Like all spiders, cellar spiders are predators. They are also very sensitive to vibrations in their webs. Spiders in this group probably use touch and chemicals to communicate, though they can see too. They are not social animals, they only come together to mate. They often hang upside down while waiting for prey to touch their webs. Most cellar spiders don't move around too much, they usually stay with their web, or raid nearby webs. We don't know for sure how long these spiders live, probably only a few years at most, and very few probably make it that long. To grow they have to shed their exoskeleton, which they do many times during their lives.
