Description: Native birches are subject to attack by insects at all stages of growth from the germinating seedling to the mature tree. All parts of the treeroots, stem, branches, foliage, and even the developing seedmay be utilized as feeding sites by insects of one kind or another. An enumeration of the many insects recorded in the literature as feeders on birch might be impressive in numbers but would contribute little to this symposium. Rather, it would seem more appropriate to consider a few representative kinds of insects that are responsible for particular types of injury, to indicate their relative importance and the need for control.
