Summary[edit]

Description
English: “Ghost” experiment. Footage shows a nonsocial observer bumblebee worker tested with the string task after the observation phase. The bee lands several times on top of the left and right tables and tries to obtain the sucrose. In getting off the table, the bee accidently moved the string sideways but did not appear pay attention to this movement. After 4 min, the bee eventually lands at the edge of the left table and tries to reach the flower by pushing her way under the table. The bee touches the string with her fore and middle legs but does not grasp or pull it. Twice, the string moves sideways because the bee walked on it, with no consequence on the flower position. The bee keeps coming back to top of the table and remains ultimately unsuccessful.
