    "abstract": "This paper presents a detailed characterization of the trajectory of a single\nhousefly with free range of a square cage. The trajectory of the fly was\nrecorded and transformed into a time series, which was fully analyzed using an\nautoregressive model, which describes a stationary time series by a linear\nregression of prior state values with the white noise. The main discovery was\nthat the fly switched styles of motion from a low dimensional regular pattern\nto a higher dimensional disordered pattern. This discovered exploratory\nbehavior is, irrespective of the presence of food, characterized by anomalous\ndiffusion.",
