Zebra Spider

The zebra spider, also known as the zebra back spider, is a species of jumping arachnid found across the Northern Hemisphere. It gets its name from the black and white stripes on its body. Although it is a poisonous insect, its venom does not have enough strength even if it bites a human.

  • These spiders lead a solitary lifestyle.
  • They are among the few spider species that do not build webs.
  • Zebra spiders are diurnal and hunt during the daytime.

Mating & Reproduction

The mating season for zebra spiders is in spring and early summer, and they breed once a year. Before mating, males perform a courtship dance that involves waving its front appendages (exclusive to males) called pedipalps and moving its abdominal region up and down. If the female likes the dance, mating occurs, which involves the male transferring sperm into the female organ known as epigyne.

Life-cycle

Females guard the hatchlings, and after the latter go through their second molt, they become independent of their mothers and live by themselves. Male zebra spiders reach sexual maturity before the females.

Lifespan

Information regarding the lifespan of these spiders in their natural environment is limited. However, they live for around 2 to 3 years in captivity, with females outliving males.

Communication

Zebra spiders communicate through visual, olfactory, chemical stimuli. They also use vibrations to perceive their environment.

Adaptations

  • The zebra spider is believed to have the best eyesight in the insect world, with four large forward facing eyes that give it excellent stereoscopic vision. The remaining four eyes are arranged in such a way that allows the spider to see around its body. This aids them both in catching prey and escaping predators.
  • They can jump as well they can by straightening the fourth, rearmost pair of legs suddenly. The velocity of the jump is estimated to be around 2.1-2.6 feet/second (0.64-0.79 meters/second).
  • The coloration of these spiders helps them stay camouflaged.

Predators

Mantises and spider wasps are known to prey on zebra spiders.

IUCN Conservation Status

The IUCN is yet to assess the zebra spider.

Interesting Facts

  • Their scientific name is a mixture of the Latin word ‘Salticus’ which means dancing, a reference to the zebra spider’s agility, and the Greek word ‘scenicus,’ meaning a decorative place or theatrical, referring to the showy coloration.
  • They are one of the few insects that show human awareness. If someone looks at them, they often raise their heads, and their behavior changes as well.
