Prinsip spesies: Bored Tunnel
Bore it yourself.
Persistent, careful effort can quietly shape sturdy homes and shared habitats.
A female Xylocopa chews a near-perfect round tunnel into dead wood at roughly a couple of centimetres a day, then partitions it into brood cells with walls of chewed pulp; the same gallery is often reused and extended by her daughters across generations.
