Borers

Timber borers are insects that feed on a wide variety of seasoned, dry, decaying or dead trees. There are also borers that attack living trees and fresh timber. Adult wood borers lay their eggs on a suitable tree, where the eggs will hatch into larvae that excavate the bark. The larvae of some species tunnel into the wood of the tree. Once development is completed, new adults will emerge through an exit hole that they chewed up. 

Wood borers play an important ecological role in the decomposition of trees via the holes that they produce and the fungi that they bring with them. Because of this behaviour, they also damage structural wood and wooden furniture in urban and rural areas, therefore, making them pests.
