Flightless dung beetle
|Flightless dung beetle|
The flightless dung beetle (Circellium bacchus) is a species of dung beetle endemic to a few areas of South Africa, including the Addo Elephant National Park and the Buffalo Valley Game Farm. It is the only species in the genus Circellium.
The species was originally widespread in Southern Africa, but it only survives in the few areas mentioned above; as such, it qualifies as an IUCN vulnerable species. Its vulnerability is exacerbated by a number of other factors, including the fact that its habitat is under threat by agriculture and human activity, that it has low breeding capacity as well as low dispersability (as a consequence of being flightless), and that its survival is strictly dependent on a number of vertebrates (particularly elephant and buffalo) that are also experiencing a decrease in population.
