The Red Oak Borer Beetle makes a mess of good timber, wreaking havoc on the industry.
The larvae of this beetle bore into weak, but still living, Red Oak and White Oak wood. Oak trees that have been cut down for human use (flooring, cabinets, furniture, etc.) and allowed to dry in lumber yards has become prime real estate for the Red Oak Beetle. Despite its name, this beetle takes advantage of many kinds of oak trees. It is considered a major pest to the timber industry because the larvae compromise the strength and integrity of the wood, rendering it useless and wasted for its original purpose. While still usable for other purposes, the quality is almost cut in half and the price timber companies can ask for the wood depreciates at a loss for the business. Removing infested trees from the pile can and has greatly helped reduce the damage to standing logs. Signs of infection/infestation are easy to recognize with practice (bark discoloration, shavings of frass kicked out of the tunnels by the larvae, weeping sap, etc.).
Like all Longhorn Beetles, the Red Oak Borer Beetle has antennae that are much longer than the beetle's actual body. (The orange coloring on the face in some of the photos is believed to be a mass of mites or other small insect and does not have any relation to the name of the Red Oak Borer.) They are brown and tan and covered with fine hairs.

Size (Adult; Length): 9mm to 27mm (0.35in to 1.05in)
Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Antennae: Beetles have a pair of antennae on the head used as sensors.
Head: The head is home to the insect's eyes, antennae, and mandibles (jaws).
Thorax: Holds the three pairs of legs as well as vital internal organs.
Elytron: One of two wing cases on a Beetle that protects its wings (plural: elytra).
Wings: Appendages used for flying and kept under the elytra until needed.
Abdomen: Houses organs related to circulation, reproduction, and excretion.
Legs: Beetles have three pairs of legs located at the thorax, numbering six legs in all.
