Zebra Spider Bite

Zebra Spider Bite. The Zebra Spider is a northern hemisphere species that is also known as the Zebra Jumping Spider. They are adapted to chance predation by waiting for unsuspecting prey and then suddenly jumping on them to capture, similar to other jumping spider species. They do not build a web to catch prey.

The zebra-like black and white coloring gives them their name.

What is a Jumping Spider?

The ability of the jumping spider to leap and catch prey gives it its popular name. The Salticidae family of jumping spiders includes them.

With roughly 300 species in the United States and Canada, including the zebra spider, Salticus scenicus, there are more than 4,000 recognized varieties of jumping spiders throughout the globe.

Zebra spider

The Salticus scenicus, a common Northern Hemisphere jumping spider, is known as the zebra jumping spider.

Their scientific name comes from Salticus, which is Latin for “dancing,” and the Greek scenicus, which means “theatrical” or “of a beautiful location,” in reference to the species’ vivid black-and-white coloration.

Males are 5–6 mm long and females are 5–9 mm. The chelicerae of male zebra spiders are noticeably bigger than those of females.

Although the anterior and posterior lateral eyes (ALE, PLE) are also large when compared to the relatively tiny posterior median eyes (PME), spiders in the Salticidae family have especially enlarged anterior median eyes.

The huge anterior median eyes are primarily responsible for its superb binocular vision, and there are eight of them in total. These tiny spiders have white stripes on their bodies due to the black hairs.

The little spiders that jump zebra are called zebra jumping spiders. Their bellies are striped with a black and white pattern. Jumping spiders have the finest eyesight of any arthropod, and they belong to a different subfamily of spiders.

In the front, they feature massive eyes with three smaller eyes on either side (as seen in the photos below). They can concentrate and rotate their eyes, as well as estimate distances.

Zebra Jumping Spider Habitat and Habits

Zebra spiders may be observed in sunny locales, such as along the sides of homes or in gardens near human-inhabited locales, and may be found throughout most of the globe.

These spiders may pounce on prey and escape predators by leaping in all directions. They pounce like a cat as they sneak up on their victim.

They grasp themselves to a surface before pouncing, enabling them to return if they miss and try again, and generally hunt prey that is their size or slightly bigger.

Mosquitoes, which are two times the length of the spiders, have been known to be eaten by them. They participate in more sight-based hobbies, such as the males’ intricate mating dance for females, because of their great eyesight.

Web retreats, which are loosely woven, saclike structures composed of many envelopes, are built by jumping spiders rather than snare webs. Molting, hibernation, nighttime seclusion, and egg-laying are all activities that take place during these retreats.

The egg sacs, which hang from the retreat’s wall like a hammock, are typically lens-shaped. Underneath furniture, in drapery folds, between books, on wood floor cracks, and around doors and window moldings are all common hiding places for jumping spiders.

Outside, among bark and between leaves, jumping spiders hide.

Zebra spiders mate in May, and eggs are produced in June and July throughout the New England states. There are 15-25 white eggs in each zebra spider egg sac. Older spiderlings are thought to overwinter in a shelter and emerge as adults in the spring.

Since there are more insects attracted to these areas, adult male zebra spiders can be found from April through July and females can be found from mid-May until late October.

While racing over tree bark, beneath stones, on bushes, and along fences and decks, they are also frequently seen in sunlight areas.

These spiders prefer to live indoors on doorways, walls, and windows, so they are frequently seen in gardens.

This species is typically seen hunting on the walls of buildings where the sun warms the surface, and it is commonly found around urban and suburban areas. In or around the following places, zebra jumping spiders are especially common:

-Inside and on the exterior of buildings.

-Rock walls.


-Under stones.


-High grass.


Hunting spiders that do not weave a web to capture prey are known as zebra jumping spiders. Instead, at their nighttime hiding spots, they utilize the internet to guard the egg sacs. The Zebra jumping spider’s prey includes any bug or other spider that it can overpower.

The scientists do not yet have precise knowledge on the number of offspring a zebra jumping spider has and the amount of time between egg deposition and independence. An egg sac, which is usually covered by a rock, protects the spiderlings as they develop.

Spiderlings become autonomous of their mother during their second molt and start living by themselves. Before their female counterparts, the males of the species reach sexual maturity.


When the angle subtended by the prey exceeds 5.5°, they orient towards it detected by their lateral eyes. The computation of reactive distance takes into account only moving things, not the velocity of the victim.

The size of the target and the speed with which it is being pursued determine the likelihood that orientation will be stalked. As it approaches its (stationary) prey, the zebra spider’s stalk velocity decreases progressively.

They attach a silk thread to the ground they’re jumping from before leaping, so if they miss the target, they can climb up the thread and try again.

Yet, if they want to safely descend from a height, such as by ‘abseiling’ from ceilings, they may ‘abseil’ with a silk thread. Unattractive insects like ants are ignored.

Joint extension in the spider leg is regulated by haemocoelic blood pressure, so there are no extensor muscles at the ‘hinge joints.’

The leg spines raise during the jump, a consequence of rising body pressure that may be seen on many spiders, which is the most compelling proof that this expansion is due to hydraulic forces.

The fourth pair of legs abruptly straightens, causing the zebra spider to jump almost fully. Between 0.64–0.79 m/s (2.1–2.6 ft/s) is assumed to be the mean jumping velocity.

How does a zebra spider catch its prey?

Several strategies are used by the zebra spider to capture prey. The zebra spider, which moves slowly toward its victim before pouncing on them, relies on its large front eyes to locate and pursue prey.

This hunting technique is likened to that of a cat. Their acute vision enables them to determine precisely how far they must leap and capture the prey.

They climb up the silk thread and try their luck again if they miss, thanks to a sticky silk thread that helps them leap to their victim. Ants are unpalatable to them.

Do Jumping Spiders Bite?

Unless they feel threatened, jumping spiders seldom bite. When it comes to their survival, they have the ability to bite.

The symptoms of a jumping spider bite are minor. Bites might be asymptomatic, which means you won’t experience any symptoms. These don’t seem to be as serious as a bee sting, and they resemble mosquito bites.

When the bite into your skin, you might experience discomfort in uncommon circumstances. Redness, stinging, and swelling may all occur as a result of this.

Wash the bitten region with water and soap if you get bitten. Next, a cold compress may be used to control any swelling. Take aspirin and acetaminophen to alleviate the discomfort if you still have symptoms from a jumping spider bite. Adults are the only ones who can use these pain relievers.

If the signs get worse, seek medical attention right away.

How to Treat a Jumping Spider Bite

One of the most prevalent spider species is the jumping spider. Just 300 of the thousands of jumping spider species found in the United States are indigenous. Even if you get bitten by a jumping spider, it is not dangerous to humans.

When a spider is being crushed or threatened, it will usually bite. These stings are thought to be less harmful than a bee sting, and they might cause a little mosquito-bite-sized welt (if you have any symptoms at all), according to the University of California Davis.

These bites, on the other hand, may cause health issues if you are allergic to jumping spider venom or if the spider that bit you was not a jumping spider after all.

This guide will teach you everything you need to know about how to treat a spider bite and when it is appropriate to see a physician.

You can treat the bite at home if you’re fairly certain that the spider that bit you is a jumping spider. Here’s what to do first:

Soap and water should be used to wash the spider bite. To avoid any bacteria from accessing your skin barrier, this will help to prevent an infection from developing later.

Apply a cool compress (such as a wet washcloth) to the location of the spider bite if you experience a burning sensation. This can help relieve the symptoms of puffiness, redness, or discoloration.

If a welt develops around the site of the bite, you might want to apply a topical antibiotic ointment.
If the above first aid measures fail, you may want to try other at-home treatments for the bite, such as an antihistamine cream or a topical analgesic.

Are Jumping Spiders Dangerous to Humans?

Human beings are safe from jumping spiders. They’re carnivorous, but human flesh isn’t their target. Instead of eating bigger insects and spiders, they consume similar or smaller ones.

When they sense they’re being trapped or afraid, they can be harmful.

How to Prevent Jumping Spiders From Entering Your Home

Free-roaming jumping spiders can be prevented from entering your home with minimal effort. While pursuing their prey, jumping spiders prefer to live outside, but may wander indoors by mistake.

Dry habitats don’t appeal to jumping spiders. In the spots with suspected leakages and water concerns, you may run a dehumidifier to dry them out. Spiders will be discouraged from entering or remaining in your home for a long time.

Jumping spiders may also be prevented from entering by using one of the following methods:

-If you can’t find a solution on your own, call in a professional pest control company. Several chemicals and equipment are available to these firms, which are not readily accessible on the market.
-Using caulks to secure all crevices and cracks.
-Sealing windows and vents.
-Screening vents.

The fastest strategy is to see a healthcare professional as soon as possible if you aren’t certain whether a jumping spider has bitten you. They can assist you in identifying and managing the symptoms of a jumping spider bite.

Do zebra spiders bite humans?

Is it safe to be around them? These spiders will not bite unless they are handled or otherwise threatened, so they are not aggressive biters. Although they are tiny, these spiders do produce venom, which is utilized to subdue their meal. Human Venom Is Only Severely Injurious

Are zebra spiders friendly?

Humans are generally not endangered by jumping spiders, which are harmless. These small jumpers, despite their carnivorous natures, are scared of humans.

Can zebra spiders jump?

The Zebra spider, which can jump up to 10cm (over 14 times its own body length), is a common jumping spider that stalks and leaps on its prey. Look for it in gardens and occasionally in houses, on walls, rocks, and tree trunks in the sun.

Can zebra spider bite humans?

Are They Dangerous? Unless they’re handled or threatened in some manner, these spiders aren’t aggressive biters and won’t bite.

The zebra jumping spider’s bite venom is only likely to cause minor injury to humans because the spiders are so small.

Did You Know

Salticus is derived from the Latin term for “dancing” as a allusion to the male’s acrobatic abilities, while scenicus is derived from a Greek word that means “decorative location” or “theatrical.”
One of the few insects that has knowledge of humans is this spider. This spider is occasionally observed raising its head and exhibiting other behavioral changes when an individual looks at it.

How many eyes do they have?

They are, nonetheless, members of the Salticidae family, which includes an enlarged anterior median eye and bigger anterior and posterior lateral eyes in comparison to the tiny posterior median eyes. It is important to remember this. The zebra spider has eight eyes, according to these statistics.

The superb binocular vision is aided by one eye in particular: the exceptionally huge anterior median eyes.
