A cottager was standing beside a cut log and he was hearing a loud, crunching sound coming from somewhere. It sounded like a beaver or large animal grinding a set of big teeth on a piece of wood. But there was nothing to be seen. Eventually, he was able to track the sound to a cut log that lay on the ground in front of the cabin. Pulling back some bark, one single, monstrous white grub was found. It was approximately 3 inches long and it had enormous mandibles that it was using to cut and eat the wood under the tree bark. Many grubs and insects are harmful to trees and it is wise to try to eradicate them. Ash borers are a good example. Invading species such as these can wreak havoc on a forest where they have an ample food supply and no natural predators. But most beetles and grubs are beneficial and do no harm. Such is the case here. It is the larvae of a large, Pine Sawyer beetle.
