This species occurs in most of southern Africa, but only in uplands north of the Tropic of Capricorn. Kenyan and Tanzanian populations have now been removed from this species, thought to refer instead to Cacosternum plimptoni. Presumably the populations in Ethiopia (where it occurs mainly to the east of the Rift Valley, with isolated populations to the west) should also be seperated, but for now they are treated as C. boettgeri. Its presence in Angola has not been confirmed. It occurs up to 2,500 m asl in Ethiopia. Its range might have increased during the last century due to human activity.
Habitat and Ecology
It is a species of grasslands (including montane grassland) and dry savannahs, favouring open areas with short vegetation, and is extremely successful in grassy meadows. It breeds in any shallow water body, including vleis, flooded depressions, drainage ditches, puddles, small pools, inundated grasslands and shallow pans, especially where grass is growing. They have been found in large numbers in disused termitaria.
It is extremely common and occurring in almost all suitable habitats throughout its range. It is usually present in high densities.
It is a supreme generalist, and it adapts extremely well to disturbance.
It occurs in many protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats and its presumed large population.
This form consists of many cryptic species. We follow Channing et al. (2005) in removing Kenyan and Tanzanian population from this species, under the name Cacosternum plimptoni. Ethiopian populations should presumably also be separated as a distinct species, but for now we treat them as part of C. boettgeri.
