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. Another commonly found inside homes is the Parson Spider. The narrow, shiny black spider has two black spinnerets at the tip of its abdomen that are shaped like tubes. In general, all Ground Spiders forego weaving webs to trap prey. They run it down instead. Retreats spun from spider silk are built for resting between hunts.
Ground Spiders are great stalkers and fast runners, capable of startling humans that observe too closely. Females lay eggs in a silky sac that is guarded until the offspring hatch. They are not considered aggressive, choosing to focus their attention more on finding the next meal rather than on nearby people.
Scientific Name: Zelotes duplex
Size (Adult; Length): 8mm to 15mm (0.31in to 0.59in)
Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Legs: Spiders have four pairs of legs and these are attached to the cephalothorax.
Pedipalps: Small appendages near the mouth used as taste and smell organs.
Cephalothorax: Contains eyes, head, mouthparts, and legs.
Abdomen: Contains various organs related to digestion, reproduction, and web-making.
Spinnerets: Used in the production of spider silk for fashioning webs or catching prey.
NOTE: Unlike insects, spiders have both an endoskeleton (internal) and exoskeleton (external).
