Hello! Thanks for maintaining this cool and informative site! I saw what I think is a Brown Marmorated Stinkbug at my home in a suburb South of Seattle. It’s the second one this year, and I saw one last year as well. Can you possibly confirm? And if it is a Halyomorpha halys, should I report it to my state agricultural authority? I know they are known in Eastern Washington, but I’m not sure about the Puget Sound area. Thank you!

Brown Marmorated Stink Bug

Dear Jason,
This is indeed an invasive Brown Marmorated Stink Bug.  The species has spread so far, so quickly in North America (see BugGuide data map) that it has begun posing a serious threat to some agricultural crops and many ornamental plants and fruits and vegetables in home gardens.  Contacting your state agricultural authority at this time is probably not necessary.  We know the species is most likely here to stay.
