Which insect is referred to as a round-headed borer due to the large, oval holes it creates in wood?

The longhorned beetle is referred to as a round-headed borer because it creates large, oval holes in wood as part of its life cycle. Adult longhorned beetles generally lay their eggs on or near wood, and upon hatching, the larvae burrow into the wood to feed. This feeding activity causes distinctive oval-shaped exit holes when the mature beetles emerge, leading to the common name "round-headed borer." The destruction caused by these beetles can result in significant structural damage to timber and wooden structures, making identification and management of this pest important in pest control practices.

In comparison, while termites and carpenter ants also damage wood, they do not produce the same type of exit holes characteristic of longhorned beetles. Termites create mud tubes and tend to consume wood from the inside out, which does not result in large, visible exit holes. Carpenter ants excavate wood for nesting but typically leave it relatively clean, resulting in small exit holes and debris rather than the large, oval holes associated with longhorned beetles. Woodboring bees, on the other hand, may create holes, but they typically do not have the same impact on wood structure as longhorned beetles and are not classified as
