The Oak Cordwood Borer, Xylotrechus nauticus

A home in Sonora had an interior support post, approximately eight feet tall, made from the truck of an oak tree. This oak wood had the bark removed, and there were large, emergence holes in it. The beetle that did the damage was the oak cordwood borer, Xylotrechus nauticus. Specimen collected by David Katosic, 13 July 2017.
