Carpenter Bees

"I'm a carpenter bee and I dig a tunnel in wood that becomes a nest for my brood..."

Excerpt from: Can You See If I'm A Bee? By Melissa Garrick Edwards

 


Carpenter Bees

 

Carpenter bees get their name because they usually excavate tunnels in wood to build their nests in. Some carpenter bees and bumblebee queens are the largest native bees in the United States. They don't eat the wood they carve, but they can cause damage to structures that are dry, weathered, and in need of replacement. 

 

Carpenter Bee Habitat

 

Carpenter bees are not social insects like honey or bumblebees, which is why they don't live in hives and create individual nests in trees, eaves, or sides of structures. They overwinter in old nest tunnels and in the spring they emerge to mate. While the mated female chooses a suitable piece of wood for her nest, the male spends most of his time protecting the nest site by hovering and chasing intruders away. The female makes a tunnel using her mandibles and then furnishes her nest with a mixture of nectar and pollen called "bee bread." She lays an egg and then chews the wood into a pulp to plug the nest cell with. 

 

Carpenter Bee Behaviors

 

Male carpenter bees don't have stingers but act threatening while protecting a nest. Female carpenter bees usually won't sting because they'll die and won't be able to take care of their eggs. If someone is allergic to bee venom and is stung by a carpenter bee, they should seek medical attention immediately.
