Eucalyptus Tortoise Beetle

Eucalyptus woodlands, forests, gardens, and urban areas containing host trees. Native to Australia and introduced to regions like California.

Herbivorous; both adults and larvae feed extensively on the young foliage and leaves of Eucalyptus species.

Adults are oval, dome-shaped beetles that cling tightly to leaves and glass surfaces using specialized tarsal pads. They undergo complete metamorphosis, laying eggs in clusters on host foliage. When threatened, adults can retract their legs and antennae beneath their hardened shell.

Risks: Can cause significant defoliation to ornamental Eucalyptus trees and commercial plantations. Benefits: Serves as a food source for native insectivorous birds, predatory bugs, and parasitic wasps.
