Brown Marmorated Stink Bug (Nymph)

Natural Habitat

Originally from East Asia, now invasive in North America and Europe. Found in orchards, gardens, residential areas, and often seeks shelter indoors during colder months.

Diet & Feeding

Polyphagous herbivore; feeds on fruit trees (apples, peaches), vegetables (peppers, tomatoes), and ornamental plants by piercing the tissue and sucking plant juices.

Behavior Patterns

Nymphs often cluster together after hatching. They progress through five instars before adulthood. Known for releasing a pungent, coriander-like odor when disturbed or crushed as a defense mechanism.

Risks & Benefits

Risks: Major agricultural pest causing damage to crops (fruit scarring, cat-facing). Nuisance pest indoors as they aggregate in homes to overwinter. Benefits: None significant in introduced ranges; prey for some generalist predators.
