What is a stinkbug?

  Stinkbug or field bug is a common name applied to any of the hemipterous bugs con­stituting the family Pentatomidae, characterized by a nauseating, persistent odor which protects them from their enemies and which remains on plants over which the bugs walk. The family contains over five thousand species, about five hundred of which are native to the United States. Stinkbugs are broad, flat insects with five-jointed antennae. They are usually green, gray, and brown; some are colored bright red and black or bright yellow and black. Stinkbugs vary in their food habits, some being exclusively carnivorous and others being exclusively plant feeders. One of the most familiar species of Stinkbugs is the destructive cabbage bug.
