I fear not!
This is probably an adult brown marmorated stink bug, Halyomorpha halys, a 'recently' introduced species that is known mostly for swarming on and in homes at this time of year as they seek places to overwinter. I don't know that this species is recorded yet from Delaware, so you should contact the state department of agriculture and attach these images with your e-mail. It may prompt an attempt to eradicate these bugs if they are indeed H. halys. Thanks.

Brown Marmorated Stinkbug?
I have been trying to ID this "beetle" for some time as they keep showing up. I'm in central Jersey and first ran came across them last season. I have kept a specimen and I'm reasonably sure this is what it is. As this is my first time at this I'm not sure what should what be done?
Is there someone to be advised or contacted to verify what this "bug" is?

Status update, USDA directive
I received reply from DE Plant Industries Administrator "Thank you for notifying us of the stink bug find. From the photos, it looks like the Brown marmorated stink bug. The white rings in the antennal segments are quite diagnostic. About 2 years ago, there was a confirmed find of this insect in Newark, Delaware. This was reported to NAPIS, the national system that tracks the distribution of agricultural pests. Your find in Bear is the farthest south in the State that we've heard about. While this stink bug is an agricultural pest in its native country of China, we don't know how its pest status will play out in the US. We do know that it can become a pest for homeowners in the fall, when it seeks refuge from the cold in windowsills and casings. The USDA has elected not to make the brown marmorated stink bug an actionable pest for quarantine or eradication. So for right now, the best we can do is to track and monitor it."

Halyomorpha halys
Eric, thank you for the ID and the alert. I have contacted Delaware Government Information Center and Delaware Department of Agriculture. Thanks again, Ted
