I. Introduction
Goal of the project:
► Make behavioural experiments on butterflies► Explore sensory abilities ► Identify role of internal status like hunger-level, egg-load etc► Explore memory and learning effects► Butterflies either memorize or mark host plants visited ► Explore inference and anticipation

II. Flight cage and cameras:
► Near natural environment in a flight cage► Cameras record movements of the butterflies

III. Image and data processing
► Image processing detects butterflies and determines flight trajectories► Statistics give insight into the behaviour of the butterflies► Identify decision rules► Create and improve movement model

V. Conclusion
Already promising first results:
► Test flight cage and consumer cameras show viability► Image processing is still to be developed ► Explore memory and learning effects (in the future)► Explore inference and anticipation (in the future)► Define and improve movement model (in the future)► Compare model to measured trajectories (in the future)
