There are over 5,000 species of stink bugs worldwide, and they range in color from drab green and brown to brightly-colored red and yellow. Most species suck juices from trees and shrubs, but a few prey on other insects. As a result of their feeding habits on commercially-valuable crops, some species are serious pests to humans.

Stink bugs are also known as shield-bugs because of the shape of their bodies. They have broad “shoulders” that taper into their abdomens below their folded wings. They have strong angular legs for gripping plant stems and have specialized mouthparts for piercing and slurping. They are very common insects and can be found nearly everywhere in the world where there’s vegetation.





Stink bugs are so-named because of their defense against predators. If they’re disturbed, they will eject a noxious liquid from special glands in their thorax. The smell and taste of this bitter chemical weapon is enough to deter many predators and to put off a casual human collector. The bright coloration of many species is a warning sign to predators that it doesn’t taste very good. Sometimes coloration alone in the animal kingdom does the trick without needing to deploy the weapon being advertised.
