Flies aren’t just willfully messing up human attempts at regulation; key differences between the physiology of flies and humans encourage the mixing of different types of regulative spaces. As the 1958 Encyclopedia Britannica Film The House Fly warns, “[A fly] can not bite or sting but its physical structure and feeding habits make it a carrier of disease and death.”34 For instance, the fly has hairs on its feet that are sensitive to taste. This means that a fly can taste its food by walking on it. Humans, however, have their organs of taste more closely confined to their alimentary canal, allowing for the separation of the functions of eating and walking. This is a profound set of differences in the two organisms as it implies that humans try very hard to keep production separate from consumption, while flies need to mix these up to live.
