Rationale
The threat status of the Black-spotted Plangia is Least Concern because it has a large extent of occurrence and, due to its sporadic pest status, affinity for cultivated crops and presence within protected areas, its geographic range is not expected to be severely fragmented or to experience decline in the foreseeable future.
Threats
The greatest threat to this species is habitat destruction, but due to its widespread distribution affinity for cultivated crops and propensity to outbreak sporadically, it is not directly threatened.
Conservation
No specific conservation measures are in place for this species but it is known to occur in several protected areas, including Namaqua National Park, Jonkershoek, and Cederberg Nature Reserves.
