Brown Marmorated Stink Bug (nymph stage)

Agricultural land, gardens, and woodlands. They are known for entering human dwellings in autumn to seek shelter for winter.

Polyphagous herbivore; they feed on various plants including fruits (like apples, peaches, and grapes), vegetables, and ornamental plants using piercing-sucking mouthparts.

Nymphs undergo five instars before reaching adulthood; earlier instars (like the one pictured) are often found in clusters. They emit a pungent odor from scent glands when threatened or crushed.

No health risk to humans as they do not bite or sting, but they are major agricultural pests and a nuisance indoors. They offer no significant ecosystem benefits in non-native regions.
