Flies are disliked by everyone except in Australia. In their childhood, Australians are taught flies are clean and beautiful. Only foreign flies are dirty and troublesome. It is true that Australian flies are quite different from others. They are a little larger in size, with the body and the wings shining with golden light. Their flying produces no sound and most of them are found in the forests in the northern mountains, living on the juice of plants. As the forests are sunny all around the year, none of the flies produces their young in wet places. So the flies there are clean. Not only will Australians never try to kill flies, but also they will protect them as they protect other animals. A golden fly is drawn on the note of an Australian dollar, and the kangaroo(袋鼠) is the only other animal that can be seen on Australian notes. Flies' “high position” can be known from that. Because the Australians have loved the flies for a long time, it is natural that they have been reproducing in great numbers. In the forests, visitors often see groups of flies flying overhead. There is a saying, “Keep your mouth shut while walking in the forests or the flies will fly into it.”
But flies have many natural enemies. In the forests, many birds and bigger insects(昆虫) feed on them, controlling them from increasing.
