Natural Habitat

Found on a wide variety of plants including fruit trees, vegetables, and ornamental shrubs. They often move indoors to overwinter in climate-controlled spaces.

Diet & Feeding

Herbivorous. They feed on over 100 species of plants, using their proboscis to suck juices from fruits, leaves, and stems.

Behavior Patterns

They are known for releasing a pungent, 'stinky' odor from scent glands when threatened or crushed. They undergo hemimetabolous metamorphosis (egg, nymph, adult) and typically seek shelter in houses during fall.

Risks & Benefits

They are primarily an invasive agricultural pest that can cause significant damage to crops. While they do not bite or sting humans, their presence indoors can be a nuisance, and their defensive secretions may cause skin irritation or allergic reactions in sensitive individuals.
