Green stink bug

The green stink bug feeds on many plants, including native and ornamental trees, shrubs, vines, weeds, and soybean. The preferred hosts are generally wild plants, but as these plants mature these bugs move to soybean.
Green stink bug is a flattened, shield-shaped bug, named for the offensive odor it produces. The adult is bright green and about 2/3 inch (17 mm) long. It is easily distinguished by the triangular-shaped plate that partially covers its wings.
The nymphs hatch from clusters of barrel-shaped eggs. They closely resemble the adults throughout their several nymphal stages. However, the nymphs are wingless, black and red in color and lack the triangular plate.
Green stink bug may appear in soybean fields from mid-July through harvest time. Often they are most numerous in the border rows next to weedy or wooded areas.
