The first brown marmorated stink bug (BMSB) officially identified in Michigan was found in Berrien County in 2010. A student taking an entomology course that required an insect collection had included it with his other insects. Sometime later, as the instructor was evaluating each collection for a grade assignment, he recognized the specimen as BMSB and sent it on for positive identification. The following year, this invasive pest was found for the first time in Eaton, Genesee, Ingham, Lenawee, and Monroe counties. Then in 2012, it was first reported in the counties of Allegan, Clinton, Kent, Oakland, Oceana, and Wayne. So far, BMSB has been detected in 12 of 68 Michigan’s Lower Peninsula counties. No reports have come from the Upper Peninsula.
