Commentary

Avatar of commenter Thank you for your report! This is not EAB. It's a native member of the Metallic Wood-boring beetle family, the Golden Buprestid, Buprestis aurulenta. These beetles are larger and less slender than EAB. They are not tree killers. Their grubs live in dead conifers.

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

Thanks for being on the lookout!

Avatar of commenter Whoops, I didn't look closely enough. This is another jewel beetle, Chrysophana placida. Another native beetle in conifers, not a pest species.
