Where does feeding occur for dogwood borer?

Explanation:
Feeding occurs in living tissue just under the bark—the cambium and inner bark. The dogwood borer larvae tunnel into this area to access nutrients, disrupting nutrient and water movement within the tree and girdling it as they feed. Leaves, roots, and heartwood aren’t the feeding sites for this species: leaves are for foliar feeders, roots for root-borers, and heartwood is dead tissue that the larva does not feed on. This cambial feeding explains the typical symptoms and why this location is the correct choice.
