The dogwood twig borer is distributed in the United States of America wherever there are flowering dogwood trees. They are adaptable and although the bulk of a dogwood twig borer's diet is obtained from flowering dogwood trees, it can also feed on elm, azalea, and viburnum. Many species of fruit trees are attacked by the beetle.

Most dogwood species have opposite leaves, while a few, such as Cornus alternifolia and C. controversa, have their leaves alternate. Dogwood flowers have four parts. In many species, the flowers are borne separately in open (but often dense) clusters, while in various other species (such as the flowering dogwood), the flowers themselves are ...
The leaves are 4–8 cm (1 + 1 ⁄ 2 – 3 + 1 ⁄ 4 in) long and 1–4 cm (1 ⁄ 2 – 1 + 1 ⁄ 2 in) wide, and typically have 3 or 4 pairs of lateral veins, fewer than other dogwood species. [4] The plant grows upright with a rounded habit, oppositely arranged leaves, and terminally born flowers.
