The river birch is a fast-growing, water-loving, deciduous tree, native to much of the United States. Its scientific name is Betula nigra. Unlike other birches that have white barks, the river birch's bark is reddish brown and curls and peels naturally, adding visual interest to the plant.
The specific type of aphid that feeds on river birch foliage is known as the spiny witch-hazel gall aphid. In the spring, this aphid feeds on river birch leaves. In early summer it moves on to witch hazel foliage, but will not infest any other type of plant.
