The culprit must be precisely the adjacent windings. The bumblebees seek the sweet scent that the lindens spread, but the nectar from the tree contains too little nutrition. The bumblebees that lie on the ground are hollow, but according to Peter Nilsson this is not due to starvation, but to the progress of other insects.
When SVT comes to Folkets park, children stand around the lindens and curiously look down at what has now become a bumblebee cemetery.
