Submitter does not have a specimen

Recently saw a posting about this species attacking native twinberry in Portland. Earlier this year my landlord dug out a very large twinberry that had been dying back and I suspect this is what caused it. We have a smaller twinberry still in the yard and I found d-shaped holes on the older wood. A coworker confirmed it is definitely some kind of Agrilus.
