What behavior is common among Carpenter Bees regarding their nesting habits?

Carpenter bees are well-known for their distinctive nesting behavior, which primarily involves creating nests by tunneling into wood. These bees are equipped with strong jaws that allow them to bore into dead, sound wood, such as old fences, trees, or wooden structures, creating a series of tunnels. This behavior is specific and adapted for their nesting needs, providing them with a safe environment for their larvae.

The incorrect options highlight nesting behaviors not characteristic of carpenter bees. While some bees do nest in soil or create nests in other materials, carpenter bees are specifically known for their tunneling action in wood, making this option the most accurate description of their nesting habits. Thus, the focus on wood tunneling is a defining trait of carpenter bees and underscores their unique adaptations.
