What shape are the exit holes made by Buprestidae?

Buprestidae, commonly known as jewel beetles or metallic wood-boring beetles, produce exit holes that are broadly oval in shape. These holes tend to be longer and thinner than those created by other wood-boring insects. The unique shape of these exit holes is a distinct characteristic that helps in identifying the presence of these pests. The exit holes are typically small but their longer and narrower profile differentiates them from the round holes made by other species, such as some borer beetles that create circular holes. The understanding of the morphology of exit holes is critical in pest control and management, as it assists in diagnosing infestations and deciding on appropriate treatment strategies.
