The Western Stink Bug (Chinavia hilaris) is a common pest found in North America, particularly in the western United States. It is characterized by its shield-shaped body, which can vary in color from green to brown. These bugs are most active during the warmer months and are known for their distinctive odor, which they release when threatened. These insects primarily feed on the sap of plants, making them a concern for farmers and gardeners. They can damage crops such as soybeans, corn, and various fruits. Effective management strategies include monitoring and using insecticides when necessary to control their population.
