Jumping Spider: Facts & Common Questions

Spiders have a terrible reputation in general. The leaping spider (family Salticidae) is, on the other hand, quite adorable. That’s correct. We used the word “cute” to describe a spider. Jumping spiders are not only beautiful to look at, but they are also fascinating creatures.

Are you ready to hear some interesting facts about these cute tiny arachnids? We’ve got a lot in store for you.

But, first and foremost, are jumping spiders harmful?

Dangerous Jumping Spiders

Let’s confront the elephant in the room right now. You’re curious about the toxicity of jumping spiders. Venomous spiders, such as jumping spiders, are seen in the wild. Their poison is used to immobilize their victims.

You don’t have to be concerned about being bitten by one. When humans approach, jumping spiders are normally hesitant and will scamper — or jump — away.

Furthermore, because they can’t deliver a large enough dosage of venom to be hazardous, their venom isn’t dangerous to humans.

Fun Fact #1: Jumping Spiders Really Jump

These tiny leapers have earned their name. But they don’t merely jump around for the sake of having fun. Jumping spiders pounce on their prey, which is usually other insects, with their legs.

Jumping spiders, unlike grasshoppers, do not have unique leg muscles that help them leap. They push themselves by abruptly altering their body’s blood flow. 

A jumping spider contracts unique muscles to boost the flow of blood to its legs when it wants to soar. This causes the spider’s legs to fully expand and send it soaring — sometimes up to 50 times its body length. Isn’t it amazing?

Fun Fact #2: They’re Fantastic Dancers

Male jumping spiders perform a small dance to capture the attention of female jumping spiders. They beat their abdomens on the ground and wave their legs in the air in this dance. The spiders’ feet tap on the ground so swiftly that it isn’t visible to the naked eye.

However, those are only the easier dances. The peacock spider ups the ante by courting possible mates with a colorful fan-like extension that he sweeps around while stomping and tapping.

Fun Fact #3: Jumping Spiders Have Excellent Vision.

In the spider world, our fluffy friend has some of the best vision. Spiders with four pairs of eyes are known as jumping spiders. Two enormous eyes are in the foreground, with a smaller eye on either side. Jumping spiders have two medium-sized eyes and two smaller eyes on the top of their heads.

Those eight gorgeous eyeballs aren’t simply there to stare at you. Jumping spiders look for insects to eat with their vision. Female jumping spiders also utilize their peepers to judge male jumping spiders’ dance movements.

Fun Fact #4: They Don’t Use Webs to Hunt.

The leaping spider, unlike many other spiders, does not use a web to catch prey. Why would it need to, given its superior long-jump hunting abilities?

That doesn’t rule out the possibility of these fuzzy cuties producing silk. To defend themselves from weather or nighttime predators, some jumping spiders spin miniature tents or shelters. In addition, whenever the spider leaps, it uses a rope to anchor itself in case it misses its target.

Fun Fact #5: They Imitate Other Insects. 

The jumping spider, Myrmarachne melanocephala, also known as ant-mimicking spiders, is a master of disguise. To trick predators and prey, these tiny leapers imitate ants.

They’re longer than other jumping spiders, with slim fake waists that give them an ant-like appearance. These spiders will also adopt the hues of various ant species. They also wave two of their legs around like antennas to fit in better. Isn’t that clever?

Frequently Asked Questions:

Are Jumping Spiders Safe to Touch?

Many people think of jumping spiders as being friendly. This variety of spider is the cutest of the arachnids due to its huge eyes, front leg and pedipalp movements, and desire to “dance.” They also appear cautiously attentive, frequently studying surrounding humans before retiring to a hiding spot.

Unless they believe their lives are in jeopardy, these spiders are not hostile toward humans. Direct contact is something they avoid. Their venom is mild, and their little fangs may not be strong enough to penetrate the skin. If you compress, trap, or crush the spiders, they will bite.

What Makes Jumping Spiders Attack You?

Jumping spiders do not attack you with the intention of biting you. They may perceive you as a threat or a predator and attempt to flee by jumping. They may land on your thigh, arm, or other body parts as they flee.

Something else could have piqued the spider’s curiosity. It may leap on you to get closer to a prospective prey item, or you could just be a “bridge” it uses to travel from one location to another. This is especially true if you’ve put yourself in the way of the spider’s nest; it’s probably only trying to get home.

What is the Maximum Height That a Jumping Spider Can Jump?

According to a 2018 article published in the journal ‘Scientific Reports’, jumping spiders may leap up to 6.3 inches (160 mm) despite their small body size. 

Before leaping, spiders often spin a little amount of silk and set a thread-like “anchor,” which may help steady their flight and protect them if their landing is wrong.


As per their name, jumping spiders can jump as high as 6.3 inches. Isn’t that just amazing?

Jumping spiders have a lot of fantastic qualities which we have mentioned in this article. We hope you had a great time reading this article!
