How can you characterize the mandibles of the Old House Borer larvae?

The Old House Borer larvae are characterized by their dark brown and strong mandibles. These mandibles are well-adapted for their lifestyle, as they are designed to efficiently bore through wood, which is the larvae's primary food source. The strength of the mandibles allows them to break down the dense wood fibers, aiding in their ability to tunnel and feed within wooden structures. The dark coloration of the mandibles is a visual characteristic that helps in identifying the larvae, indicating their strong developmental adaptation for a wood-dwelling lifestyle. The other characteristics provided do not accurately reflect the physical attributes of the mandibles of the Old House Borer larvae.
