I saw one a few years ago on the outside wall/ceiling of a Cannon Beach hotel. I hope it wasn't dead, rotting wood since we're going back there soon.These beetles disappear when they're on an alder tree with thier great camouflage. They have a bold pattern but just blend right in. Being a borer you'd think they would be bad, but the eggs are deposited in dead rotting wood which the larve eat, helping decomposition. I have seen a couple on a blacktop trail near my house but have looked for and never seen one on the trees..
