How do insects feed?

There are two methods by which insects can feed:

1. Biting/chewing (jagged mandibles), like in caterpillars, grasshoppers and beetles. They can eat solid plant/animal matter, like leaves or flesh.

2. Piercing/sucking (long thin proboscis), like in aphids, mosquitos and butterflies. They can feed on liquid plant/animal matter, like sap, nectar or blood.
