Additional Information

en: Bumblebee (Bombus species unknown) extracting nectar from the rear spur of an aconitum petal.

  • Extending its proboscis through a hole bitten into the rear end of a petal to directly extract nectar is a common behaviour for bumblebees due to their a shorter proboscis. See Bumblebee#Feeding.
  • The insect thus bypasses the regular frontal route signalled by the flower and thus reduces the plant's chances of having its pollen distributed.
  • Image taken at location: own garden, Aplerbeck, Dortmund, Germany on May 30th, 2019.

  • Aufnahmeort: Dortmund-Aplerbeck, Deutschland, 30. Mai 2019.
  • Die abgebildete Einführung der Mundwerkzeuge durch ein Loch in das hintere Ende einer Blüte, um dort auf direktem Wege an den Nektar zu gelangen, tritt häufig bei Hummeln auf, die über kürzere Mundwerkzeuge verfügen.
  • Damit wird der übliche, von der Pflanze vorgegebene Zugang von vorne abgekürzt und somit die Wahrscheinlichkeit vermindert, den Pflanzenpollen zu verteilen.
  • Aufnahmeort: im eigenen Garten, Dortmund-Aplerbeck, Deutschland, 30. Mai 2019.
