Dung beetles are known to certain extent to be selective over dung or droppings. Hardly anybody has confirmed that dung beetles land on hare dung. In general, it is said that rabbit urine has some effect which makes insects shum it. We thus supposed that the same effect might be expected with hare dung. Therefore, we made a selective cxperiment on the dung of deer, wild boars and hares. The results indicated to us that dung beetles tend to gather around boar's dung in groups and that as a whole, they dislike hare's dung. In all cases in this experiment, the dung beetles used this dung and we could observe them blowing eggs and their larvae growing. Furthermore, we weighed each kind of dried dung and the result was that hare's dung was the heaviest, deer's dung came next and the lightest was wild boar's. We thus came to the conclusion that the water content of dung has a great influence on its selectivity and utility value.
