''Scathophaga stercoraria'', commonly known as the yellow dung fly or the golden dung fly, is one of the most familiar and abundant flies in many parts of the northern hemisphere. As its common name suggests, it is often found on the feces of large mammals, such as horses, cows, sheep, deer, and wild boar, where it goes to breed.〔 The distribution of ''Scathophaga stercoraria'' is likely influenced by human agriculture, especially in Northern Europe and North America.〔 Scathophaga are integral in the animal kingdom due to their role in the natural erosion of dung in fields. They are also very important in the scientific world due to their short life cycles and susceptibility to experimental manipulations, and have thus contributed significant knowledge about animal behavior.〔 ==Description== ''Scathophaga stercoraria'' are sexually dimorphic insects with an average lifespan of one to two months. The adult males of ''Scathophaga stercoraria'' are bright golden-yellow with orange-yellow fur on the front legs. Females are a little duller in color, with pronounced green-brown tinges, and no brightly colored fur on the front legs. The adults range from 5 mm to 11 mm in length, and the males are generally larger than the females.〔(), Blanckenhorn, W. U., Bussiere, L. F., Floate, K. D., Pemberton, A. J., & Roembke, J. (2010). “A review of the natural history and laboratory culture methods for the yellow dung fly, Scathophaga stercoraria”. Journal of Insect Science, Volume 10, Article 1.〕 The physical features of separate ''Scathophaga stercoraria'' populations can vary greatly, due in part to the range of locations in which the species is found. Generally, they are located in cooler temperate regions, including North America, Asia, and Europe. They may also favor higher latitudes, such as the Swiss Alps, and higher altitudes, such as the Pyrenees.〔(), Blanckenhorn, W. U., Bussiere, L. F., Floate, K. D., Pemberton, A. J., & Roembke, J.
