Thank you for your report! Yes, that is EAB. You are located right in the known infested area in Forest Grove.

EAB attacks ash trees, olive trees and white fringe trees, all in the olive plant family. 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

This website will also give you the response plan for EAB in Forest Grove. Thanks for being on the lookout!

Amber, you can access the OSU Extension Forest Pest Detectors Program at the link below. They will be updating and expanding the course in the fall, but the current information is accurate and you can take it as many times as you like.
