Chrysomelidae - Leaf beetles

Astheir common name suggests, leaf beetles eat plants. Most are colorful,conspicuous beetles, frequently restricted in their feeding to one or afew similar plant species.

WhileWhile 10 species of leaf beetles are known from Coal Oil Point, noneseem to be restricted to coastal habitats. Some, like the Cucumberbeetle (Diabrotica undecimpunctata)are very widespread. One species of particular interest is theeucalyptus feeding Trachymela sloanei. This species was newly (andaccidentally) introduced to our area from its native Australia in justthe past few years. For fans of non-native eucalyptus, this beetle isconsidered a pest. For others who consider eucalyptus itself aninvasive pest, the beetle is a welcome ally. A beautiful metallic greenspecies, Trirhabda luteucinete, is abundant in the spring time and can be seen, as adult or larvae, on coyote brush, its host plant.
