Definition & Meaning of "leaf beetle"

What is a "leaf beetle"?

A leaf beetle is a small insect that belongs to the family Chrysomelidae. It is named for its feeding habits, as it primarily feeds on the leaves of plants. Leaf beetles come in a variety of colors and patterns, ranging from metallic hues to vibrant patterns. They have a compact body shape and hardened elytra (wing covers) that protect their delicate wings. Leaf beetles can be found in diverse habitats worldwide, and many species are considered pests of agricultural crops and ornamental plants. They have specialized mouthparts adapted for chewing, allowing them to consume plant tissues. Some leaf beetles possess defensive mechanisms, such as emitting foul-smelling chemicals or playing dead, to deter predators.
