Abstract
Beinwell. Der Nektar ist aufgrund seiner Lage für Bienen und kurzrüsselige Hummeln erst zugänglich, nachdem "erfahrene" Hummeln durch die Basis der Blütenröhre ein Loch gestoßen haben. Die Bestäubung erfolgt durch Pollensammler.
Robbery of nectar, happening often in certain types of flowers, is demonstrated in this film with Symphytum officinale.
