Plant feeders

Insects that feed on plants

A lot of insects feed on plants. Some of them feed by chewing on leaves (like grasshoppers), fruits (like some beetles), or stems (like the larvae of some beetles); others by sucking the liquids inside the plants (like true bugs and leafhoppers; others by sucking on the nectar (like butterflies and moths) or by eating the pollen of flowers.


Grashoppers feed by chewing on the leaves of plants.


The insect display includes some representatives of the family Romaleidae.

True bugs

The mouthparts of true bugs are like a straw that they use to pierce through plant tissues to suck the liquids inside the plant.
