Which of the following borers is often referred to as 'metallic wood borers'?

The term "metallic wood borers" typically refers to beetles in the family Buprestidae, commonly known as flatheaded borers. These beetles are characterized by their glossy, metallic coloration which enhances their distinctive appearance. They are known for boring into the wood of trees and shrubs, creating tunnels that can damage the plant structure and lead to disease or death in the host plant.

Flatheaded borers have flat, elongated bodies that contribute to their name, and their larvae go through a development process that involves boring into wood, which can be problematic for both healthy trees and those already weakened by other factors. Their striking metallic colors are not only visually appealing but also serve to differentiate them from other wood-boring insects, such as roundheaded borers and longhorn beetles, both of which have different physical characteristics and ecological significance.

Understanding the specific identification and classification of pests like flatheaded borers is crucial for implementing effective pest management strategies in structural pest control.
