Submitter does not have a specimen

Description of specimen

I am relatively sure the insects that I observed were the emerald ash borer unless there are other species of insects that are remarkably similar. I had not read the article when I observed them, so I did not capture one, but I am keeping my eyes out for another opportunity.

Commentary

Thank you for your report! There are a number of iridescent green look-alike beetles in Oregon that are not pests. I am attaching a link to the ODA EAB webpage with some photos of Oregon insects that could be mistaken for EAB

Finding infested trees before they are too far gone is difficult. Emerald ash borer makes D-shaped holes about 1/8" wide. Here is the address of Oregon Department of Agriculture's IPPM Survey and treatment projects EAB page

Scroll down to find the EAB Response Plan for Oregon and more information about how to recognize EAB attack, so that you can monitor your trees.

Location

We have an 80 acre parcel that has 26 ish acres of mixed woodland. We have Oregon Ash among the species. The insects were in the forested area flying about. Several landed on me prior to reading an article that identified them as the emerald ash borer.
