Another Year Of Brown Marmorated Stink Bugs

The ubiquitous, Brown Marmorated Stink Bug (Halyomorpha halys). Or simply the BMSB.

It is for sure ubiquitous around my cabin now. It is their season it seems. Certainly their season to try to enter homes to spend the winter. This photograph is just a few of the BMSBs on a window screen, waiting for an opportunity to sneak, to squeeze, to enter my cabin in any way possible. Many are successful, making them quite the invasive pest. They’re also an agricultural pest, an economic threat to farmers.

The Brown Marmorated Stink Bug is originally from East Asia, including China, Japan, and Korea. It hitched a ride somehow to the this continent but it isn’t known exactly how. It was first seen in Allentown, Pennsylvania, in 1996, and can now be found in many parts of North America.

There are some native creatures that will prey on BMSBs, including other insects, birds and spiders.

I was really pleased to witness an Orb Weaver that had captured this BMSB, wrapped it up in its silk and was proceeding to eat it. In this picture the Stink Bug is up-side-down and the Orb Weaver is underneath, on the left side of the image. I really hope the spiders that are spinning their webs to decorate my cabin for Halloween are eating many, many of these ubiquitous pests!
