How are Drywood termite galleries typically described?

Drywood termite galleries are typically described as sculpted due to the way these termites excavate the wood. The term "sculpted" conveys the idea that the galleries have a refined and specific structure that showcases the termites' behavioral patterns of tunneling. When drywood termites bore into wood, they leave behind a very distinct pattern of galleries that is often smooth and polished, with edges that are fairly clean. This is a result of the termites' feeding habits and the manner in which they remove wood fibers.

The use of "sculpted" emphasizes not just the physical appearance of the galleries but also suggests a certain artistry to their construction, making them different from the more chaotic or random patterns seen with other types of wood-destroying insects. In contrast, descriptors like rough or irregular do not accurately capture the characteristic appearance of drywood termite activity, as their galleries are methodically formed.
