Brown Marmorated Stink Bug

Natural Habitat

Originally from East Asia (China, Japan, Korea, Taiwan), it has become an invasive species in North America and Europe. It inhabits agricultural fields, orchards, gardens, and urban/suburban environments, often seeking shelter in homes and buildings during colder months.

Diet & Feeding

Polyphagous herbivore, feeding on a wide variety of plants, including fruits (apples, peaches, pears, berries), vegetables (corn, soybeans, tomatoes, peppers), ornamental plants, and field crops. They use their piercing-sucking mouthparts to feed on plant sap, causing damage to fruits and seeds.

Behavior Patterns

Risks & Benefits

Risks: Major agricultural pest, causing significant economic damage to crops. Nuisance pest when they invade homes. Benefits: No known direct benefits, their impact is overwhelmingly negative as an invasive species.
