The Chrysomelidae – Leaf Beetles

The Chrysomelidae – Leaf Beetles are a family of beetles with about 37,000 species.

Leaf beetles are distinguished by their variety of colors and shapes, as well as by their size, which can vary significantly from one species to another. Many leaf beetles are relatively small, but some species can reach larger sizes.

These insects are often associated with plants, as many species of leaf beetles feed on leaves, stems, and flowers of various plants. Some can cause damage to agricultural crops and ornamental plants, while others play important ecological roles as pollinators or in regulating plant populations.

Leaf beetles have a variety of lifestyles and feeding habits. Some are strict herbivores, feeding exclusively on specific plants, while others have a more generalist diet. Some are known for their ability to secrete toxic chemicals or emit a foul odor to defend themselves against predators.
