Halyomorpha halys
Obvious white bands on antennae and legs on older nymphs.
The brown marmorated stink bug (BMSB), Halyomorpha halys (Stål), is an invasive alien insect native to Japan, Korea, Taiwan and China. It was accidently introduced to North America in the mid 1990s, and was first identified in Allentown, Pennsylvania in 2001. It has been found in most states and several Canadian provinces, though many of these are detections rather than confirmed as established in the field. Large populations exist in several Mid-Atlantic States, where BMSB is considered a significant agricultural and nuisance pest. BMSB is an excellent hitchhiker and can be moved over large distances in shipping containers, cargo and vehicles. It has been intercepted on a wide variety of trade goods coming into Ontario and other provinces from infested areas. BMSB is established in parts of southern Ontario and it is anticipated it will continue to spread.
