Brown marmorated stink bug

Halyomorpha halys (Stål)

Pentatomidae: Hemiptera

Distribution: Current distribution is from northeastern PA, NJ and MD south to SC and west to WV, but expected to increase as this is an introduced pest.


Brown marmorated stink bug adults are 3/4-inch long and shield-shaped, with mottled brown coloration on the upper and lower surface. They can be distinguished by lighter bands on antennae and they have darker bands on the membrane part at the rear of the front pair of wings. On the head, there are patches of copper or bluish-metallic depressions. Eggs are light green and are laid in groups of 20 to 30 on the underside of leaves or on clusters. There are five nymphal stages. This pest can contaminate harvested clusters and its secretions can lead to tainted juice.
