Stinkbugs are medium-sized insects, rather rectangular-shaped, with overlapping wings on the back. They are often dull brown or green. Some species suck juices from plants, while others prey upon other insects, usually caterpillars or beetle larvae, sucking their bodily juices. The predatory stink bugs are commonly observed on various wildflowers, where they suck nectar. Predatory stinkbugs can be distinguished from other stinkbugs by the presence of blunt spines on each side of the thorax behind the head. They are called "Spined Soldier Bugs."
