If you are someone that likes to watch a lot of movies and TV shows, then you have probably seen scenes where people are wrapped in a web and die by being eaten by spiders.

These kinds of movies are mostly responsible for one of the most common phobias out there called arachnophobia or intense fear of spiders. Spiders are part of a group known as the Arachnids hence the name of the widespread phobia. They are found in every part of the world except Antarctica, so if we are going to live with them, we ought to know more about them. 

First of all, you don’t have to worry because humans are not a food source for spiders. But, now that we have established that, you might wonder, what do spiders eat in order to survive?

With that said, let’s see what’s on a spider’s daily menu.

So What does a spider eat? 

Before we ask ourselves what does a spider eat? , we must mention that there are thousands of spider species and their diet mostly depends on where they live and how big they are.

As the true hunters that they are, they like to camouflage themselves and jump on their prey when it comes in close proximity to them. They usually eat crickets, grasshoppers, beetles, etc. Lizards and frogs are also on the menu for some giant hunter spiders like the huntsman spider. Others have been known to prey on even bigger animals like birds and bats. What they all share is their love for live prey. Yes, spiders don’t like to eat anything that hasn’t been killed recently. 

In conclusion, some spider species build webs to catch food. They are also called passive hunters – they wait rather than walk around and attack. On the other hand, other species like wolf and crab spiders don’t really have the patience to wait around all day. They actively seek out and hunt their prey.

What do spiders eat other than bugs? – Plant-eating spiders.

Most spider species like their meat and don’t feast on plants. The reason behind this is that they can’t really digest it.

Among those plants there can be seeds, leaf tissue, pollen, nectar, plant sap, etc.

Among the jumping spider species, there is one that dwells on the Acacia tree and feeds off the nectar that the tree provides. This spider is mainly found in Central America.

How much they eat is another topic on its own. Studies have shown that spiders tons and tons of insects and bugs every year. A little comparison so you can comprehend the idea – they eat more insects in a year than we eat meat and fish. Some species can also go for long periods of time without eating. Crab spiders are one of them. They are so patient while waiting for their prey that they can even go for days or even weeks without eating.
