$\beta$ black phosphorous is more stable.
$\beta$ black phosphorus has a layered structure in which each phosphorus atom is covalently bonded to three neighbouring P atoms.
The atoms within the layer are more strongly bonded to atoms in adjacent layers. This gives $\beta$ black phosphorus graphite like structure.
$\alpha$ black phosphorus are monoclinic or rhombohedral crystals and are non conductors of electricity unlike $\beta$ Phosphorus.
