Do you ever feel like something is watching you, only to turn around and see a spider dart away? Spiders are masters of ambush, lying waiting for their prey before leaping out to capture them. Most spiders are relatively small creatures, with the majority measuring less than 1 cm in length.

Despite their size, many spiders are capable of jumping great distances. Some species can even jump up to 50 times their body length. In this article, we’ll take a closer look at these fantastic arachnids and find out just how they can make such impressive jumps.

About Jumping Spider Species

A jumping spider is a type of arachnid that gets its name from its ability to jump. These spiders belong to the Family Salticidae and can be found worldwide.

Around 4000 different jumping spiders are known to exist, with around 300 of those found in North America.

The most common jumping spider in North America is the zebra spider (Salticus scenicus). Jumping spiders are relatively small compared to other types of spiders, but they make up for this by being able to leap many times their body length. They use this skill not only to capture prey but also to avoid predators.

They are usually dark-colored and have large eyes that help them see their prey. If you come across a jumping spider, there is no need to be afraid. These spiders are not aggressive and will not bite humans unless they feel threatened.

Spiders That Jump

What Do Jumping Spiders Look Like?

Jumping spiders are known for their ability to jump. Some identification signs include:

  • The color of jumping spiders is usually black, but it can also be brown, tan, or gray. They have faded markings on their body.
  • They have 8 legs and a compact body shape with relatively short legs.
  • Their legs may also be different lengths, with their front legs being the longest. 
  • Adult jumping spiders typically measure 1/8 – ¾” in length (4-18 mm). It is important to note that they do not have antennas.
  • They are present throughout the United States. Now that you know a little more about jumping spiders be on the lookout for the next time you’re outdoors.

What Do They Eat?

Jumping spiders are predators and hunt their prey. Their diet consists mainly of insects and other small arthropods, but they have also been known to eat small lizards, frogs, and snakes.

To capture their prey, they will stalk it and then jump on it using their powerful legs and capture the prey. Jumping spiders are an essential part of the ecosystem because they help control the population of insects and other pests.

A rare example of a spider that eats its vegetables is Bagheera kiplingi, which specializes in noshing on the leaf tips of acacia bushes. This Central American spider’s diet makes it strange among jumping spiders.

Do They Pose A Threat To Humans?

No, jumping spiders are not dangerous to humans, and they will not bite unless they feel threatened. If a jumping spider does bite a human, it is not considered poisonous and will not cause any serious harm. However, the bite may cause some temporary discomfort or irritation. There is no need to be afraid if you see a jumping spider. These spiders are more scared of you than you are of them.

Do Jumping Spiders Really Jump?

Jumping spiders can jump because of a certain muscle located in their third and fourth pairs of legs. This muscle allows them to store energy and release it quickly, propelling them through the air. Also, their legs can store large amounts of elastic energy.

When a spider wants to jump, it will first extend its legs outwards. This stores energy in the spider’s legs, like stretching a rubber band. The spider then uses this stored energy to propel itself forward in a single explosive jump quickly.

While most spiders use webs to catch prey, jumping spiders rely on their vision and quick reflexes to hunt down their food. They can see very well, much better than most other spiders. Their eyesight is so good that they can spot prey from up to 7 feet away.

When a jumping spider sees its prey, it will first assess the distance and then make a calculated jump towards it. Once close enough, the spider will pounce on its victim and deliver a paralyzing bite.

How Good Is Jumping Spider Vision?

A jumping spider’s vision is quite good. They can see in color, and they are very sensitive to movement. This is why they can jump so quickly to catch their prey. The central eyes are their best eyes and work as a set of binoculars. A large outer lens magnifies the image from the outer lens and projects to the retina. 

The muscles of jumping spiders are attached directly to their retinas. This allows them to move their retinas up and down, focusing on different segments without any outside movement. The secondary eyes of jumping spiders provide them with crucial peripheral vision. This allows them to see their prey clearly and accurately pounce on it.

A rare example of a paradise jumping spider can see a broader range of colors than other spiders in the UV range. These spiders are more brightly colored, often in shades of red and orange. This expanded color vision is due to a genetic mutation that causes an extra copy of the gene responsible for blue/green vision. 

This extra gene has then mutated further to enable the detection of red and orange light. Such mutations also led to the development of color vision in primates.
