Description of specimen

It’s a green bug.


Thank you for your report! This is not EAB. It's a native member of the beetle family Trogossitidae ("Bark-gnawing beetles") in the genus Temnoscheila. These beetles are not so bullet-shaped as adult EAB. They are not tree killers or otherwise pests.

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 other Oregon insects that could be mistaken for EAB

Thanks for being on the lookout!
