Carpenter bees are large, solitary bees known for their distinctive black and yellow coloration. They are named for their unique nesting behavior, as they create tunnels in wood, often in untreated or weathered timber. Unlike honeybees, carpenter bees do not live in colonies; instead, each female builds and maintains her own nest. These bees play a vital role in pollination, helping to fertilize many flowering plants. While they can cause damage to wooden structures, they are generally not aggressive and will only sting if provoked. Their presence is beneficial for the ecosystem, supporting plant reproduction and biodiversity.
