Red Shouldered stink bug, both adults and nymphs of plant-feeding species are capable of injuring plants. Feeding damage is caused when they insert their piercing-sucking mouthparts into the plant, inject digestive enzymes, extract plant juices and allow entry of pathogenic microorganisms. The majority of stink bug species found in North America are plant-feeding species. However, there are many predaceous species, several of which are commonly encountered in the field preying on other insects.
