Ground Spiders are traveling predators that run quickly after prey and away from danger.

Ground Spiders are technically a group of spiders that are ambush attackers and one of the example species is Zelotes duplex. In general, all Ground Spiders forego weaving webs to trap prey. They run it down instead. They are great stalkers and fast runners, capable of startling humans that observe too closely. Females lay eggs in a silky sac.
