Movie 1.

Two examples of workers cutting a fragment from a thin ®Parafilm pseudoleaf Example 1 usual cutting behaviour with a leaf edge leaf edge 180° rotation example 2 manipulation experiment, in which a sheet of paper was introduced between the workers and the pseudoleaf to prevent leg contact with the leaf (The shown cuts were not included in our data analysis, because of the special conditions of illumination for the videos).
