What distinctive feature do old house borers have on their thorax?

• A. Fine black hairs
• B. Fine gray hairs
• C. Spiny projections
• D. Large wings

Answer: (B)

Old house borers, scientifically known as Hylotrupes bajulus, are distinguished by having fine gray hairs on their thorax. This feature is a crucial identification characteristic that can aid in recognizing these pests. The presence of these fine gray hairs contributes to the appearance and texture of their body, making it possible to distinguish them from other wood-boring beetles. Recognizing this specific physical characteristic is vital for pest control professionals, as it allows them to effectively identify the insect and understand its potential impact on wooden structures. This knowledge is essential for determining the appropriate measures for control and prevention of damage caused by these beetles. In contrast, the other attributes mentioned do not accurately describe old house borers. For example, fine black hairs or spiny projections do not apply to their thoracic structure, and while they do possess wings, the size and appearance of those wings do not serve as identifying factors for this particular species.
