- Selecting Wood: The bee looks for soft, unpainted, or weathered wood like eaves, decks, or fences. [1, 2, 3, 4, 5, 6]
- Drilling the Entry: She chews a clean, round hole (about the size of a dime) directly into the surface. [1, 2]
- Turning and Tunneling: After going in about an inch, she changes direction to tunnel along the grain of the wood. This main tunnel (gallery) grows several inches to a foot or more long. [1, 2]
- Creating Chambers: She gathers pollen and nectar to make "bee bread," lays an egg, and uses chewed wood pulp to seal off each individual cell. [1]

The Yellow-and-Black Carpenter Bee
Foraging and Pollination
1. Pollination: It is a generalist forager visiting numerous flowering plants and pollinating the flowers.
2. Nectar robbing: If a flower is too small for their large bodies, they bite a slit at the base of the bloom to steal nectar without touching the reproductive parts, bypassing normal pollination for that specific flower.
The Yellow-and-Black Carpenter Bee (Xylocopa flavonigrescens) excavates precise, round tunnels into dead wood, bamboo, or timber structures to build solitary nests. Females use strong mandibles to cut wood, line individual brood cells with pollen and an egg.
The Yellow-and-Black Carpenter Bee (Xylocopa flavonigrescens) Only females can sting, while males buzz defensively (to protect the nest entrance) without stingers.

- Woodpeckers: The most common vertebrate predator. They hear or sense bee larvae moving inside the wood and drill large holes to eat them, which often increases property damage.
- Tiger bee flies (Xenox tigrinus): Parasitic flies that lay eggs near nest openings. Their larvae crawl inside to feed on carpenter bee grubs.
