    North American Jumping Spider - (Naphys pulex)

    The small but mighty North American Jumping Spider outperforms human jumpers by leaps and bounds.

    Staff Writer (1/25/2014): 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.
