In nature, this includes rock hollows and cliffs. There are a few native species that look similar to brown marmorated stink bugs. In 2010, BMSB populations in the mid-Atlantic United States reached outbreak levels and subsequent feeding severely damaged tree fruit as well as other crops. Once established, BMSB populations can be highly localized (i.e., farms or crops two miles apart can differ greatly in terms of BMSB numbers). They feed on over 300 different plant species, including many fruits, vegetables and row crops. Antennae, abdomen, and legs have alternating dark and light bands. BMSB can be distinguished from other species of stink bugs by the alternating dark and light bands on the last two segments of the antennae, and the alternating light and dark banding on the exposed upper edges of the abdomen. They are approximately ½ to 5/8 inch long, have the typical “shield”-shaped bodies of other stink bugs, and are mottled brown to gray in color.
