Not all spiders make webs – about half of all the spider species make webs, while the other half will use other means of catching their prey. This includes ambushing, stalking, or leaping onto the target.
It’s fascinating to watch spiders create intricate webs. The primary use of the webs for spiders that do create them is for catching their animals of prey, but also for protecting their eggs and their spiderlings.
Not all spiders make webs, though. In Britain, for example, there are 37 spider species altogether and less than half of them make webs. Some of the most well-known spider species that don’t create webs include wolf spiders, crab spiders, and ground spiders.
Do All Spiders Make Webs?
About half of all spider species in the world create webs, while the other half don’t.
But even the spiders that don’t create webs might still use silk to create some structures, but they’re not the webs that web-making spiders create.
For example, these spiders will create draglines, which is a line of silk that is left behind a spider as it moves around. Other spiders create egg sacs out of silk where they’ll store their eggs and keep them protected from other predators. Other structures that they might make include nests and silk baits they might use for catching their prey.
However, they don’t create webs just like other spider species do. A web is an intricate structure from silk and the primary purpose of the web is to catch prey.
But since some spiders don’t have to rely on their webs to catch their prey, the point of creating a web is lost. That’s why they won’t create webs and will rely on other predatory techniques such as ambushing and pouncing.
Spiders That Create Webs
Here are some of the more well-known spider species that create webs.
1. Orb Weaving Spiders
Orb weaving spiders are well-known for their ability to create intricate webs in the shape of a spiral orb. These spiral orb webs are commonly found in gardens among the grass and leaves of trees.
Orb weaving spiders are typically found outdoors, and it’s very unusual to see them indoors. You’ll recognize a spiral orb web by its symmetrical structure and orb-like appearance, which is a very common web to see.
You’ll often notice the orb spider sitting perfectly still right in the middle of her web waiting for prey to fly into her trap.
2. Uloborid Spiders
Uloborid spiders are known for creating triangle-shaped webs. These webs are very thick and they connect to tree stands, where they will catch animals of prey that the uloborid spiders will then consume.
This spider is one of the rarest spider species without venom, so it has to rely heavily on its webs and its ability to create webs that are strong enough to hold the prey.

3. House Spiders
Most house spiders also create webs to catch their prey. These spiders will catch the insects around your home, that’s why you’ll see many different webs around your home. They will particularly be found in corners and behind closets or furniture.
The majority of the house spider species will create cobwebs or tangled webs. The main distinguishing feature of these webs is their asymmetrical structure and the fact that they’re often found in hidden spots.
4. Bowl Spiders
Bowl spiders belong to the group of spiders called Lyniphiidae spiders, also commonly referred to as sheet spiders.
These spiders create sheets of webs between blades of grass or branches of trees. The primary role of these webs is, again, to catch the animals of prey and get them stuck into the net where they can be finished off.
Spiders That Don’t Create Webs
Here are some spider species that don’t create webs.
1. Jumping Spiders
Jumping spiders are small, hairy spiders with a lot of colors, and they’re very good at jumping, as the name suggests. They can jump up to six times their body size, which is an impressive feat for such a small spider.
They don’t create webs as they have good eyesight, but they will create small silk strings that will enable them to jump from one location to another easily. This sophisticated jumping mechanism allows jumping spiders to catch their prey without needing to create webs.
2. Wolf Spiders
Wolf spiders also don’t create webs, which is because of their excellent ability to run and move about. They might resemble funnel weavers often, but they differ from funnel weavers in the fact that wolf spiders don’t create webs at all.
They’re one of the fastest spider species in the world, so they’re often able to outrun their target without having to rely on a web to catch it. Additionally, they use ambushing to catch their prey, as they will hide behind rocks and objects to ambush their target and surprise it.
3. Crab Spiders
Crab spiders closely resemble crabs in their body structure, which is why they’re named like this. These spiders are excellent predators, which you might not be able to guess from their appearance.
They can walk sideways, but they will catch most of their prey by sitting and waiting for the prey to come around before pouncing. This means that they won’t need to use a web to catch their animals of prey.
Can Spiders Survive Without Webs?
The web weaving spiders will not be able to survive long without webs, while other spider species that don’t create webs will be able to survive without them.
Most spiders that don’t create webs have other mechanisms that enable them to survive. Some spiders have exceptional vision like the jumping spiders, while wolf spiders are so quick that they’re able to track their targets down without catching it first inside a web.
Around half of all the spider species create webs, while the other half don’t. These spiders will use other mechanisms to survive instead, such as the ability to run fast or by having other senses stronger than other spiders.
