Thank you for contacting the Oregon Invasive Species Online Hotline and for including a picture of the specimen in question. Pictures are most helpful!

Fortunately, this is NOT the emerald ash borer, but is a native Oregon look alike called the golden jewel beetle. It is common this time of year and is very noticeable!

In comparison, the emerald ash borer is smaller, typically a third to a half an inch long, is very slender with little taper from their head to their hind end, and are solid olive to emerald green (no other colors or patterns).

Since golden jewel beetles do not pose a threat and since they are native to Oregon, you can go ahead and release it!

Thanks again for submitting! Your watchful eyes on our trees and forests is exactly what is needed in early detection preventative strategies. Your efforts contribute to keeping Oregon's trees and forests healthy. Much appreciated!
