I have mentioned before that the Addo Flightless Dung Beetle (Circellium bacchus) are among the largest in the world and that they play an important role in the ecosystem, helping to decompose the piles of dung deposited both by wild animals and stock animals. As there has been a little rain, this is a good time of the year to see them in the Addo Elephant National Park.
They criss-cross the roads in search of dung, causing some motorists to swerve to avoid them. One can also see them on the verges, as is the one in the photograph above. It is always interesting, however, to see them at work on freshly deposited elephant dung – this one really looks as if it is biting off more than it can chew, or that its eyes are bigger than its belly! Actually, these beetles can roll balls of dung fifty times heavier than they are.
Dung beetles are reliant on dung both for their own nutrition and that of their larvae. Quite understandably, they prefer fresh dung from which to form their brood balls. It has been interesting to read that studies have shown that these dung beetles use the Milky Way to navigate their way at night.
Not all visitors seem to be aware that these beetles are listed as vulnerable on the IUCN list and so do not heed the many signs warning them to give way to the dung beetles on the road. Factors such as agriculture and human interference have led to the vulnerability of these beetles – we need to watch out for them!
