Insects feed on just about anything.
Some are predatory, some are parasites, and others are blood-sucking. Most have an appetite for decaying and decomposing material. Their mouths contain very powerful jaws and needlelike parts that function as teeth. In chewing insects, the mandibles move sideways. Sucking insects have a long proboscis and require liquid food.
