What dung beetles do for us
Dung beetles perform a very necessary service to us humans with our ever increasing consumption of meat. For example, in the U. S. there is almost 1 cow for every 3 people. Each cow produces about 9 tonnes of dung a year! And how do we get rid of this dung? Well for cows reared outside we do nothing at all. The dung beetles and other invertebrates perform that service for us for free.
In Australia there are no native dung beetles, and after the introduction of cattle in the 19th century there was a massive fly population explosion because of all the piles of dung lying around for months on end. So they introduced a South African dung beetle. This greatly reduced fly numbers, which pleased both cattle and humans.
The ancient Egyptians associated the dung ball rolling behaviour of the adult beetles with their sun god, Ra, whom they believed rolled the sun across the sky, consequently dung beetles were venerated in their culture. Even today the image of the adult scarab beetle in jewellery is supposed to bring good luck to the buyer and wearer.
