Brown Marmorated Stink Bug (nymphs)

Agricultural fields, orchards, gardens, wooded areas, and frequently invades homes in cooler months.

Polyphagous, feeding on a wide variety of host plants, including fruits (e.g., apples, peaches, berries), vegetables (e.g., corn, tomatoes, peppers), and ornamental plants. Both nymphs and adults use their piercing-sucking mouthparts to feed on plant sap, seeds, and fruits.

These are nymphs of the Brown Marmorated Stink Bug, which undergo incomplete metamorphosis (egg, nymph, adult). They are often found in clusters, especially in early nymphal stages. They are known for releasing a foul-smelling liquid when disturbed or crushed, which is a defense mechanism. They overwinter as adults in protected locations, often seeking shelter indoors.

Potential risks include significant agricultural pest, causing damage to a wide range of crops, leading to economic losses for farmers. They are also considered a nuisance pest in homes, especially during fall when they seek overwintering sites, though they do not bite or pose a health risk to humans. There are no known significant benefits from this invasive species.
