Carpenter bees are solitary insects, and their breeding behavior involves a male and female pairing up to mate. After emerging from hibernation in the spring, male and female carpenter bees seek each other out for mating. The female then begins constructing a nest and laying eggs. The male carpenter bee’s primary role is to protect the female and their territory during the breeding process.

During the mating process, the male carpenter bee defends the female and their territory by aggressively chasing away other males. This territorial behavior ensures that only the strongest male carpenter bee is able to mate with the female. The male will dive-bomb intruders, emit buzzing sounds, and engage in physical combat if necessary.

Once the female carpenter bee finds a suitable location for nesting, she begins constructing a nest. Carpenter bees create nests by drilling perfectly round holes into wood with their mandibles. These tunnels, called galleries, can be up to 10 feet long. The female deposits an egg inside each gallery and provides provisions such as pollen and nectar for the offspring. She then seals the tunnel with sawdust to protect the developing eggs from predators and harsh weather conditions.
