Thank you for your report! This could be a devil's coach horse beetle, but it could also be one of several similar species of rove beetles in the family Staphylinidae. While Devil's coach horse beetles are not native to Oregon, they are not considered invasive and are widespread in our area. No action is needed.
Regards,
Lindsey
