Birch trees are adored for their light foliage and peeling bark. While most people think of the white bark varieties, there are birch trees with gorgeous bark in shades of orange, red, or yellow, too. They are hugely popular trees, but there is a nasty pest that threatens birches, in the shape of the bronze birch borer.
The bronze birch borer is a wood-boring beetle whose larvae cause huge damage under the surface. They feed on the tree's vascular system and essentially starve the tree from the inside, causing thinning foliage, bare branches, dieback, and ultimately death.
