What’s on the menu?

Spiders are known to eat a variety of foods. Web-building spiders commonly consume flying insects such as flies, mosquitoes, moths and butterflies. Hunting spiders, as their name implies, lie in concealed areas and attack their prey as it comes near, while other spiders are fast enough to run down, capture and eat insects such as crickets, grasshoppers and beetles.

What do spiders eat other than bugs?
