Natural Habitat

Found on a wide variety of host plants including fruit trees, ornamentals, and agricultural crops; often seeks shelter inside buildings or homes during cold autumn and winter months.

Diet & Feeding

Herbivorous, using piercing-sucking mouthparts to feed on fruits, vegetables, and seeds, which causes structural damage to the plants.

Behavior Patterns

Notable for their defensive ability to release a pungent-smelling fluid from scent glands when threatened. They are highly mobile and are known as 'hitchhikers,' spreading easily across regions via cargo and vehicles.

Risks & Benefits

Considered a major agricultural pest that can destroy crops. They are a nuisance to humans when they congregate in homes, although they do not bite or transmit diseases to people.
