Episode: Ein Raubtier, das von Nektar lebt

Wespen sind vermutlich 70 Millionen Jahre alt. Meist bilden sie Staaten, einige von ihnen leben auch als Robinsone. Als Erwachsene sind sie Raubtiere. Alles, was sie zu sich nehmen, muss flüssig sein, so schmal ist ihre Taille. So verfüttern sie die Beute an ihre Larven und trinken dann deren Speichel als Nektar. Der Biologe Prof. Dr. James Hunt erforscht die Evolution dieser komplexen Tiere. In Zusammenarbeit mit dem Wissenschaftskolleg in Berlin.
