The small but mighty North American Jumping Spider outperforms human jumpers by leaps and bounds.
Jumping spiders are opportunistic, ambush predators. They do not weave webs for catching prey, but they can make spider silk. These little spiders are harmless to humans, though their fierce jumping ability startles most people. It is not unusual to find them on curtains, sofa cushions, corners and walls, actively searching for bugs to eat. They do not even need a running start to leap distances greater than 3 or 4 times their body length.
Like a cat, the North American Jumping Spider pounces on insect prey and uses a silken dragline to pull the prey to itself. Female jumping spiders also use silk to wrap their eggs into a sac and affix it a hidden crevice, corner, or hideout.
Scientific Name: Naphys pulex
Size (Adult; Length): 1mm to 4mm (0.04in to 0.16in)
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).
