Hi Tim, thanks for your report. I have shared it with the OSU insect identification lab - I'll get back to you as soon as I get a response. Thank you.

Hi Tim, the insect pictured is a Prionus beetle, definitely not the Invasive European species Tetropium fuscum (commonly known as the Brown Spruce Longhorn beetle). Prionus beetles feed on the roots of trees and shrubs as larvae and are native to the PNW. For more information on Prionus beetles visit:
