Hungry spiders eat up to 800m tonnes of insects a year!

Lots of people are scared of spiders, even some Newsround presenters, but they are actually really helpful creatures.

According to a new study the world's spiders eat up to 800 million tonnes of insects every year.

That's the same amount of meat and fish that humans eat over twelve months.

It might seem like spiders are greedy but actually they are helping humans and saving us from disease-carriers and pests like flies and insects.

As well as being incredible hunters they are also food for lots of other animals like birds and lizards.

Scientists estimated that there are a total of 25 million tonnes of spiders on Earth.

Then they worked out how much food the spiders need to survive.

So the next time you see one maybe you'll look at it in a new light.
