English: String pulling training Step 3. Footage shows a bumblebee in training Step 3 obtaining sucrose solution from a fully covered flower positioned at the edge of the table. The bee lands on top of the table and immediately repositions herself in front of the table. Then, she starts extending her proboscis in between the flower and the table whilst manipulating the string with her middle and forelegs, grasps the edge of the flower with her forelegs, and pulls it with both legs alternately. Once the flower is extracted, she steps onto it, moves her forelegs and middle legs back and forth while pushing with her head against the edge of the table to slide the flower out, and obtains the reward as in Step 2.
