Stinkbugs
various species

Adults are green, gray, or brown; shield-shaped; and about 15 mm long. The body appears hardened except for the rear portion of the forewings, which are overlapped over the rear of the abdomen. Young nymphs are rounded and convex like ladybugs and are often found in clusters or groups. Older nymphs resemble the adults but have no wings and are slightly more rounded. Both adults and nymphs suck sap from buds, pods, seeds, or fruit causing deformed or shriveled seeds and fruit. Host plants: alfalfa, beans, cow peas, cereals, peas, corn, fruits.
