Latest Wisconsin Insect: Brown Marmorated Stink Bug

The hits just keep coming, in the form of more uninvited 6-legged visitors whose real home is across the seas.

A surge of invasive species has washed over our Greenwood neighborhood Pewaukee and Wisconsin in the past two decades: the Japanese beetle and Asian beetle to name a few. All are innate to foreign countries. All have caused environmental and economic havoc in the U.S., where no natural predators exist to control them.

The most recent invader winging its way here will literally make a stink.

The brown marmorated stink bug is ¾-inch long, with a wide back side that tapers to a point, and a rectangular head with long antennae. Native to China and east Asia, the insect has been migrating west since being first discovered in Pennsylvania in 2001.

Its name is well-deserved. When smushed or crushed, the brown marmorated stink bug emits a strong, nasty you'd invite into your Greenwood home, right?

Fortunately, the brown marmorated insect hasn't arrived in great numbers in Greenwood or WI. Stink bug control isn't much of an issue yet. Yet it's only a matter of time.

Farmers hate them for more than their stink. The stink bug feed on tree fruits, vegetables, sweet corn and soybeans. Mid-Atlantic apple growers sustained an estimated $37 million in crop losses in 2010 to marmorated stink bugs.

The Asian invasive has a cousin that is native to the United States. The brown stink bug looks a lot like the brown marmorated version, except the colors of their undersides are different. We somehow doubt you'll get that far identifying them, though.

Brown marmorated stink bugs like to winter inside Greenwood homes. If you crack one, you'll figure it out quickly. The nose knows.
