Spiders are a beneficial species that can help keep insect pests at bay. They are predators that feed on a wide range of insects, including beetles, wasps, and leafhoppers.
In addition to catching their prey, spiders use silk, a natural fiber, to build webs and wrap eggs. Many spiders also use their webbing to trap other insects.
While spiders are an excellent predator, they are not particularly helpful to the average person. Some people are terrified of spiders. However, learning the purpose of spiders can make them less intimidating.
Spiders have eight legs and six joints on each leg. To survive, they must eat other animals. There are about billions of spiders in the world.
They are found on every continent except Antarctica. Most of them start hunting in the early spring. It is not unusual for spiders to eat up to 2,000 insects a year.
Spiders are known to be aggressive, territorial, and able to kill their own kind. However, most spiders are not able to harm humans. A few are very dangerous. These include black widows and long-legged cellar spiders.
If you have been bitten by a spider, try not to panic. You can use an over-the-counter antihistamine to help with your symptoms. Additionally, elevate the area you were bitten and apply a cold compress. Until you are able to see a doctor, do not eat the bite.
Arachnophobia is the third most common phobia in the United States. The number of flies would be astronomical without spiders.
