Analysing the behaviour of flying insects, like flies and bees, promise to give insight into the mechanisms that allow them to accomplisch aerobatic flight manoeuvres and solve orientation tasks in complex environments. Video recording with high-speed cameras constitutes an appropriate technique for studying the behaviour of the insects while influencing them least possible. The resulting flight trajectories illustrate the complexity and variability of behaviour which generally complicates the extraction of principle mechanisms. My research interest lies in the analysis of behavioural data using data mining techniques for generating manageable, quantitative, and comparable descriptions of behaviour as a basis for discovering behavioural principles.
