Natural Habitat

Typically found on legumes like soybeans and kudzu vines, but they are notorious for swarming homes in autumn and spring seeking shelter.

Diet & Feeding

They feed on sap from the stems of plants, particularly legumes. Their primary host is kudzu, but they are a significant pest of soybeans.

Behavior Patterns

They exhibit 'swarming' behavior in the fall as they look for overwintering sites, often congregating on light-colored walls of houses. When disturbed, they often play dead and drop.

Risks & Benefits

Risks: They are a major agricultural pest for soybean crops. For homeowners, they are a nuisance pest that can stain fabrics and emit a foul odor when crushed. They do not bite humans.
