What is the overwintering stage of dogwood borer?

Explanation:
Dogwood borer overwinters as a larva living inside the tunnels it has bored under the bark in the tree. The tunnel and the bark shield the larva from winter cold, allowing it to survive until spring when it resumes feeding, then pupates and later becomes an adult moth. In contrast, eggs would not survive winter as eggs, and adults are active only in warmer weather. So the larva inside its tunnel is the overwintering stage.
