Is This Brown Marmorated Stink Bug?

I am getting a lot of emails with photos from keen reps who think they have found Brown Marmorated Stink Bugs (BMSB).  I think it is awesome that everyone is taking this pest seriously and keeping an eye out for it in the fields but they are quickly learning that there are many other stink bugs that look very similar.  So far we have not found any BMSB in our traps or in our field surveys in Ontario this summer.  The only confirmed finding is still the one adult stink bug found in a home near Hamilton this spring.  Though I expect there to be more of them out there in Ontario in the next few years, until they start to increase in population, it is going to take some time for everyone to get used to identifying them from other stink bugs.

I’ve put together some slides to compare the look a likes to help you out in the field.   Any tiny first instars can not be identified by a photo and need to be sent in to me or my colleague Hannah Fraser (OMAFRA-Vineland) for ID.  If you think  you have BMSB, please contact us.
