Brown Marmorated Stink Bug
Halyomorpha halys
- Order & Family
- Hemiptera / Pentatomidae
- Size
- Approximately 12.7 mm to 17 mm (0.5 to 0.67 inches) in length.
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.
