What Are Stink Bugs?

The scientific name of Pentatomidae derives from the fact that stink bugs have antenna which are divided into five distinctive sections. The nickname "shield bug" comes from their broad, triangular bodies which are used like a shield to defend themselves from predators. They get their common name of "stink bug" from another defensive tactic. When disturbed or attacked by predators, stink bugs secrete an offensive-smelling liquid from their thorax glands. Individually, stink bugs are not usually considered as pests. When in groups, however, they may cause serious damage to plants and crops.
