Selected images for brown marmorated stink bug (Halyomorpha halys )
The Brown marmorated stinkbug is native to Asia. It is known to be established in Pennsylvania, New Jersey, and Oregon. Hosts include maple, serviceberry, birch, butterflybush, pepper, pecan, catalpa, hackberry, redbud, citrus, dogwood, cucumber, fig, sunflower, honeysuckle, tomato, apple, plum, pear, rose, lilac, linden, viburnum and grape. Adults emerge from overwintering in April. Eggs are 1/16 of an inch, pale green and laid from June to August. Most egg masses have about 25 eggs. The nymphal stages do not have developed wings. All instars have deep red eyes. Size ranges from 1/8 to 3/4 of an inch as the insect grows and molts. Nymphs are first red, turning almost black, and then finally becoming brown as adults. They are the typical "shield" shape of other stink bugs, almost as wide as they are long. Injuries caused by feeding produce small necrotic areas on the outer surface of fruits and leaves. Scarring is common on fruits such as apple and peach. On other plants may have roughly circular stippled areas about 1/8 inch wide. Only one generation has been observed; however, there are likely to be multiple generations as it spreads south. Adults begin overwintering at the end of September and become a nuisance as large numbers congregate and invade buildings in search of overwintering sites.
