Bronze Birch Borers live mostly in Birch trees. But they especially live in Paper Birch trees.
None. Bronze birch borer bore into paper birch trees. Other insects eat the insides of the leaves of river birches. The are called leaf miners.
The scientific or taxonomic name would be Agrilus anxius.

The first indications of birch miner infestation are small green spots on the leaf surface, usually noticeable in May or June, which develop into ugly brown splotches. A birch leaf miner infestation rarely kills birch trees on its own but it is disfiguring and can weaken a tree. The leaf miner season begins in late April to mid May with eggs laid in slits on the upper surfaces of birch leaves. Of the number of pests which are attracted the birch trees, the bronze birch borer is the most important as it is both lethal and difficult to control. Evidence of borer infestation is a progressive thinning of the crown of the tree beginning at the top. Trees generally die after about two or three years, that is, after two or three infestations by the larvae. If caught early enough, there are insecticides available to prevent new infestations of the borer but these will not kill larvae already active in the tree. Insecticides such as dormant oil control only the egg stage. Trees with advanced crown loss will not benefit from insecticide use and should be removed. The good news is that healthy, well-situated, well-maintained birches are more resistant to the borer. Females prefer to lay eggs in the sunlight and are less attracted to trees whose trunks are shaded. The insects are also attracted to tree wounds and so care should be taken to avoid damaging the bark of trees.Image Courtesy Canadian Forest Service
