The Western Bug, also known as the Western Stink Bug, is a type of insect belonging to the family Pentatomidae. It is commonly found in North America and is recognized for its shield-shaped body, which can vary in color from green to brown. These bugs are primarily herbivorous, feeding on the sap of plants, and can be a nuisance in agricultural settings due to their potential to damage crops. In addition to their agricultural impact, Western Bugs are known for their distinctive odor, which they release when threatened. This smell is a defense mechanism that helps deter predators. They typically become more noticeable during the fall as they seek shelter indoors to escape the cold weather.
