Natural Habitat

Originally from East Asia, now invasive in North America and Europe. Frequently enters homes and structures in autumn seeking warmth; found in agricultural fields, orchards, and gardens during summer.

Diet & Feeding

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

Behavior Patterns

Known for aggregating in large numbers on or inside buildings during cooler months to overwinter. When disturbed or crushed, they release a pungent, unpleasant odor as a defense mechanism.

Risks & Benefits

Risks: Major agricultural pest causing fruit deformation ('cat-facing') and crop loss; nuisance pest in homes due to overwintering habits and smell. Benefits: None significant; serves as prey for some predators like birds and spiders, though often avoided due to taste.
