Is this a marmorated Stink Bug?

10 years ago

I am in SE Michigan, and I am house sitting for a neighbor. This critter was just found sitting on their couch in the window, sunning itself. If it is a Brown Marmorated Stink Bug, the state is requesting notification when they are found in this state.

My neighbors have recently moved here from Northern California and have no plants, so it worries me that it shows up in December inside the house!

Yes, that is the brown marmorated. The key identifying feature is the white bands on the antennae.

Ken seldom, if ever, posts to the insects forum.

Thank you! I was fairly certain. I guess I shall be sending a note to the state. Don't know if they have been reported in Oakland county before, but the MSU site asks to report them when found. :/

They are well established in Michigan; that they manage to find their way into homes is one of the things that they are famous for. As a matter of fact, more are reported in the winter than in the summer, in most locations.

They congregate in sheltered areas for overwintering.....one insect settles in and releases a "come one, come all and gather here with me" pheromone. They do not feed on anything inside over the winter nor do they reproduce.
