Green shield bug or stinkbug

Green Shield Bug mate by establishing contact between their rear end opposing each other.
Some stinkbugs use special odors to attract mates. Smelling the odors helps partners find each other. Some kinds of stinkbugs also attract mates with sound. They rub their legs or wings against their bodies to make noises similar to those of crickets. Mates are drawn to the sounds.
After mating, a female stinkbug lays batches of eggs. Often she lays them in neat rows of 12 or 14 eggs each. The eggs are usually laid on plant leaves. Stinkbug eggs look like tiny barrels. The colors of the eggs depend on the type of stinkbug that laid them. Green stinkbugs, for example, lay yellow to green eggs that turn pink or gray.
