Natural Habitat

Found in gardens, orchards, agricultural fields, and often enters homes and structures during the colder months to find shelter.

Diet & Feeding

Herbivorous; it uses piercing-sucking mouthparts to feed on a wide variety of plants, including fruits, vegetables, and ornamental trees.

Behavior Patterns

This species is known for its 'stink' defense mechanism, releasing a strong odor from glands on its abdomen when threatened or crushed. They are highly mobile and are known to hibernate in large aggregations inside man-made structures.

Risks & Benefits

It is a significant agricultural pest that can damage crops; while it does not bite or sting humans, it can be a major nuisance in homes due to its odor and sheer numbers in winter.
