The key characteristic of flathead beetle damage is that these insects create tunnels in trees and feed under the bark. This behavior stems from the larvae's development, as they burrow into the wood, resulting in extensive galleries that can compromise the structural integrity of the infested tree. The damage caused by flathead beetles is often more severe than that of other wood-boring insects due to their feeding habits and the size of their tunnels.

While other choices describe damage characteristics that can be associated with different types of wood-boring insects, they do not specifically align with flathead beetle behavior. For instance, the creation of small round holes is more typically associated with other insects like the round-headed wood borers. Surface discoloration might indicate damage from various pests, but it is not the main indicator for flathead beetles, whose impact is more internal and less visible until significant damage has occurred. Lastly, saying there are no detectable signs does not apply, as flathead beetles generally leave evidence of their presence through the tunnels they create and sometimes through visible frass (wood dust). Thus, option B accurately reflects the nature and impact of flathead beetle infestations.
