Stink bugs like the Green Stink bug (Chinavia hilaris) are large, oval or shield-shaped insects. They are members of the insect order Hemiptera. They get their common name from the odor of the chemical that they produce in glands on their abdomen. This odor is a defense against predators.
Many species of stink bugs feed on plants. Green Stink bugs eat a wide variety of plants. In fact, they eat just about anything. Some of their favorite food sources are Black Cherry, Flowering Dogwood, Evergreen Blackberry, and pine trees. They will suck juices from leaves, flowers, fruits, and stems. They have sharp mouthparts which they use to pierce the plant. Some stink bugs become serious pests of crops. When they attack fruits, like peaches, they make the fruit unfit for sale.
Stink bugs overwinter as adults and become active in spring when temperatures rise above 21C.
