About the bronze birch borer:

Bronze birch borers are metallic-colored wood-boring beetles about 1/2 inch long. The larvae feed on the phloem and the cambium of birch trees (Betula), causing the trees to die. The phloem is the inner bark and the cambium is "the growth layer producing both the phloem and xylem" (source). The tunneling by the larvae causes the flow of sap to be reduced.

Adults lay eggs in bark crevices from May to June. Ten days later, the larvae hatch. Pupae emerge as adult beetles the following spring. They live for one or two years overall. River Birch (Betula nigra) and healthy birches are more resistant to these pests. Bronze birch borers are native to North America. Woodpeckers are the primary predator. The bronze birch borer is closely related to the emerald ash borer.
