Dung beetle (Circellium bacchus)

Did you know?

That dung beetle benefits from national parks by the fact that the roads have been paved tourist? To roll their dung balls through or out of a gravel road or in the surrounding soil to bury the ball and complete their life cycle, can be caught in rows that accumulate the periodic maintenance of gravel roads. This makes the beetles spend much energy trying to push the ball over mounds of earth and exhausted having, sometimes, to leave the balls. They are also very sensitive to extreme temperatures, and are vulnerable to being caught on the road when temperatures are rising. Tar roads have no batteries and therefore do not present these obstacles.

Dung beetles feed on the dung of large mammals, or eat fresh manure in the place where it fell, or make a ball buried for later use. The female manure also used for the construction of a reproductive ball. She pushes him away using their powerful hind legs, while the male follows behind. At an appropriate place, bury the ball, with the male on it. Mate in the ground and a single egg is placed inside the ball. The female stays the ball to the juvenile stage of their offspring is completed. The larva feeds on the dung ball from the inside and goes from 3-4 months as a pupa before emerging as an immature adult. These large beetles, 22 to 47 mm long, not only have vestigial wings flying, that do not support their weight on the flight. Therefore, the beetles have to walk a mound of manure to another for food and collect the droppings they need to build the balls of dung. Dung beetles prefer the bulk of elephant, rhino and buffalo.Previously, the species is widely distributed in the former Cape Province and extended north into the Transvaal. As elephants, rhinos and buffalo became extinct in this region, the beetles were restricted to the Addo National Park, where small herds of buffalo and elephants survived.
