The brown marmorated stink bug is a species of tree bug. It is native to China, Japan, Korea, and other Asian regions. The nymphs and adults are considered agricultural pests. They feed on over 300 species of plants, such as fruit, vegetables, berries and field crops.
The species was introduced as a neozoon to North America (2002 in Pennsylvania) and later to Europe, where it has already been detected in Germany, France, Greece, Italy, Austria, Hungary, Switzerland, and Spain.
Adult marmorated stink bugs are approximately 1.7 cm long and about as wide. They can be distinguished from other stink bugs by the presence of distinctive white bands on the last two antennal segments. The brown marmorated stink bug uses its piercing mouthparts to suck plant juices. The nymph stages – one is shown in today’s photo – are black or very dark brown.
