On September 29, 2006, at the Botanical Gardens in
Lyon,
France, a
Nepenthes truncata was photographed containing the decomposing corpse of a mouse. This incident is the first record of a mammal being successfully trapped in the pitchers of
N. truncata indoors. Both
N. rajah and
N. rafflesiana are known to occasionally catch small mammals in the wild. Although it is possible for
Nepenthes truncata to trap mice, the calcium heavy bones will not be digested. Nepenthes truncata plant.jpg|An
