Scientific name: Halyomorpha halys

The brown marmorated stink bug is a relatively new pest for the Chicago area. There are many species of stink bug, but they are not all pests. Some are predators feeding on other insects and some are plant pests but do only minor damage. BMSB is non-native, and was introduced from Asia.
