Comments :Apparently the first record from Liechtenstein. This species can be found on cow pastures, but is more abundant in parks and at lake-shores. S. punctum reproduces in all kinds of animal dung and other decaying substrates, but seems to be particularly attracted to dog excrements. In Switzerland, males are larger than females (which is not the case in North American populations: Puniamoorthy et al. 2012) and range in colour from dark brown to partially bright yellow/orange. Intrasexual aggression is commonly observed between males, whereafter larger males are more likely to mate with afemale ( Puniamoorthy et al. 2012 ).
