Cape Flightless Dung Beetle

Circellium bacchus

Also known as Addo Flightless Dung Beetle, Flightless Dung Beetle

These robust, jet-black scarabs navigate the semi-arid thickets of South Africa on foot, having traded the energy expense of flight for a sealed, moisture-trapping subelytral chamber that prevents dehydration. Pairs often contest nutrient-dense dung dropped by elephants and rhinos, carving out spherical brood balls and pushing them backward over uneven ground with their bowed hind legs. Their relentless tunneling and dung burial aerate compacted soils while cycling critical organic matter back into the arid landscape.

What to notice
Look for a large, rotund, matte-black beetle lacking a split wing case, crawling along reserve trails.
Support conservation
Stop vehicles when beetles are on tracks and allow them to pass without physical intervention.
Responsible observation
  • Yield Right of Way: Drive slowly on gravel reserve roads where beetles frequently cross with dung balls.
  • Observe Without Touching: Leave rolling pairs undisturbed to avoid disrupting critical reproductive efforts.
