Many spiders will build webs to catch prey but there are lots of spiders who prefer to hunt, and they use their webs for other things. All spiders are born to spin. They don’t need their parents to teach them how.
Spiders that build the circular webs that we, in Canada, usually find in our yards are called Orb-Web spiders. These webs look like bike wheels and are very sticky. These are the webs that trap insects for food. Many of these spiders will build new webs every night. Others will just keep repairing their damaged webs. The spider will sit near the center of the web and wait for insects to land on the web. Some species of Orb-web spiders will weave fancy looking webs. Scientists think that the patterns help birds to see it and avoid flying into it. Another type of web is the sheet-web. This web is spun horizontally and has special non-sticky lines above it. These lines knock insects down onto the sheet-web where they get stuck. Some other spiders spin funnel-webs. These webs are shaped like…you guessed it…funnels. They are wide at the top and get narrower as they go down. The spider hides at the bottom of this web waiting for its prey. All of these webs are designed to catch food. Since spiders do not have great eyesight, they usually use the vibrations of the web strands to locate their prey. When they do, they rush on over and wrap their victim in silk, turning it around and around until it is covered. Then the spider pokes its fangs into the insect and shoots poison into it, which turns its guts into liquid, the spider then sucks out the liquid. Yuck! |
When you think about where Spiders live, the better question to ask would be where don’t they live? Spiders are able to live just about anywhere and that is why there is such diversification out there. They are ranked at #7 when it comes to the most diversified living creatures in the world. That gives you a good idea of the spectrum of how they have branched out. The only place in the world where you won’t find spiders is in Antarctica.
You will be able to find Spiders living in very dry climates. Some of them have evolved to the point where they don’t need to be around any water at all. They can survive in some of the harshest conditions you could imagine. They get the water they need from their food sources. The tropic regions are also home to many species of Spiders. Not only are they able to thrive in the climate, they are also able to find plenty of food resources for them to enjoy. These living creatures are known as terrestrial as they almost always live on land. They may be found in trees, on plants, and even living in the blades of grass in your yard. Spiders are quite versatile and they do well in all types of habitat. They do have to find shelter though when the cooler temperatures settle in. Otherwise their body temperature can change too much and they will die. This is why there are times of the year when you may see them plenty and others that you don’t see them around at all. It can be tough to fully identify any Spider habitat if you aren’t really looking for them. They blend in very well to their natural surroundings. They are able to chance colors too if they need to in order to blend in with what is all around them. Not everyone believes that the Spider can live in the wetlands but they do. Some live along the edges of lakes and ponds too. They don’t need the water or the moisture there. Instead, this location offers them a prime area to be able to find lots of food and shelter. It is a winning location for them that helps them to be able to thrive. Spiders are even making their home in your home! It doesn’t matter how clean you are or how much you look for them.

They may be in areas such as crawl spaces, the back of a closet, and even outside in a pile of bricks. If you have lots of clutter in your home though you are offering even more spaces that make an ideal Spider habitat. Many Spiders live a much longer life in captivity than they do in the wild. However, it depends on how they are cared for. Some of the larger spiders don’t do well being trapped in a small area. They also become very aggressive if they are touched often due to their heightened senses. Food supply has a great deal of influence in the Spider habitat. This is why you will see some of them in certain areas and not others. They need to be able to build their webs and have enough prey coming along for them to survive. Otherwise they have to look for a new location where those needs can be met. As humans continue to disrupt the natural habitat of the Spider, they are also branching out in new locations. This is why even dangerous spiders are sometimes seen in places that they never were before. They can get into food shipments and other containers as well. This gives them the chance to find mates and to start to thrive in places that were once vacant of such species.ay be in areas such as crawl spaces, the back of a closet, and even outside in a pile of bricks.
