A member of Salticidae, this spider jumps to ambush its prey instead of creating webs. They are fast runners and spring on top of the insect they plan to eat. As they leap toward them, a strand of spider silk is shot at the insect to keep it in tow should the spider miss its target. This strand is called a dragline. They also use their spider silk to make little shelters out of dead leaves and other debris when they are not actively hunting. They are believed to overwinter and hibernate in large groups together until spring.

The Tan Jumping Spider is known to be friendly when handled gently by humans and it has a reputation for being curious about people. They are not inclined to bite, but may do so if handled roughly. They have keen vision; the best out of what we know regarding spider sight.
