This looks like Trachykele blondeli which is a native woodboring beetle that gets into redcedar and sometimes juniper and cypress. It does not directly cause tree death. Although it may attack wood products such as poles and shingles it's pest status here is low. Insects wander in search of food and mates all the time so they may be found in areas that seem out of place.
