Gnaphosidae are reddish, brown, gray, striped, black spiders, and include nearly 2,000 described species in over 100 genera, distributed worldwide. This makes the family the seventh largest known. New species are still being discovered. They are closely related to Clubionidae. Common genera include Gnaphosa, Drassodes, Micaria, Cesonia and Zelotes. Generally, ground spiders are characterized by having barrel-shaped anterior spinnerets that are one spinneret diameter apart. All ground spiders lack a prey-capture web and generally run prey down on the surface. They hunt at night and spend the day in a silken retreat.
