Re: Beetle ID
I was at a covered bridge in western oregon (Ritner Covered Bridge near Wren), and saw thousands of these beetle coming out of cracks in the wood. Can you please identify this beetle, and tell me if they are feeding on the Douglas fir wood used for the trusses?

This is not a beetle, but a Box Elder Bug. They form very large aggregations of thousands of insects. They were not feeding on the bridge, but more likely beginning to hibernate. Perhaps as cold weather began, they sought shelter, but emerged on a warm sunny day. They often enter peoples’ homes in search of a good hibernation site.
