Phellopsis porcata processed this one to submit to BugGuide and liked it enough to post it here too. I hope someone over there can shed some light on this strange guy, as I am pretty stumped.
edit - love BugGuide - it took about a minute for someone to come up with this guy. As far as I can tell it's a very good ID, only one species possible. Geotagged,Phellopsis porcata,Spring,United States

Distribution

California, Nevada, Alaska, Idaho, Montana, Oregon, Washington, USA; Alberta, British Columbia, Canada.
Phellopsis porcata Not even sure where to begin with this one… searched for beetles that look like wood chips, warty beetles, pitted beetles and I'm not even getting close enough to start narrowing it down…. BugGuide to the rescue! Geotagged,Phellopsis porcata,Spring,United States

Behavior
