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 though they can make spider silk. They are harmless to humans, though their fierce jumping ability startles most people. They do not need a running start to leap distances longer than 3 or 4 times their body length.

The North American Jumping Spider pounces on insect prey and uses a silken dragline to attach to the prey. Female jumping spiders also use silk to wrap their eggs into a sac and affix it somewhere inconspicuous.

A Note About Territorial Reach: Keep in mind that 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. Insects are driven by environmental factors, food supplies and mating patterns and do not nescessarily work within hard-and-fast territorial lines like we humans do.
