Where do flathead borers primarily feed?

Flathead borers primarily feed internally in the trunk, branches, and roots of trees and shrubs. Their larvae tunnel into the wood, causing significant damage as they feed on the inner tissues. This feeding behavior can weaken the tree or shrub, making it more susceptible to disease, stress, and eventual decline. The distinctive tunneling patterns left behind can also indicate the presence of these pests.

The other options do not accurately represent the feeding habits of flathead borers. For example, these pests don’t feed on leaves or flower petals, which are typical feeding sites for other herbivores. Additionally, while exposed stems may attract some pests, flathead borers specifically target the wood structure of plants rather than feeding externally. Understanding the specific feeding habits of flathead borers is essential for effective pest management and control strategies.
