Pests in Gardens and Landscapes

Seasonal development and life cycle—Leaf beetle

Many species of leaf beetles feed in groups when young, then individually as they mature. Most leaf beetles pupate on the ground or attached to foliage or bark, and overwinter as adults in debris or protected places, such as bark crevices or inside buildings. Most species feed only on a few closely related plants.
