Natural Habitat

Vegetation, orchards, gardens, woodlands, and buildings; native to East Asia and invasive across much of North America and Europe.

Diet & Feeding

Pierces plant tissues and sucks sap from fruits, vegetables, ornamentals, and woody plants, often damaging crops.

Behavior Patterns

Adults overwinter in sheltered structures and emerge in spring; they produce multiple generations in warm regions. When disturbed, they release a strong defensive odor and may aggregate in large numbers.

Risks & Benefits

A major agricultural and household nuisance that can cause fruit deformation and crop losses. It does not bite or sting, and its ecological benefits are limited; native predators may consume some individuals.
