The European silver birch is an attractive tree with ornamental varieties that grow easily in a variety of soils.
It has been widely planted in parks, gardens and town squares in Europe and other parts of the world, particularly in North America, Australia and New Zealand.
Euceraphis betulae has been introduced on silver birch to all these places. In North America it still feeds only on European silver birch and ignores the native North American birch species.
