ABSTRAKPitcher plants (Nepenthes spp.) included in carnivorous plants which are often visited by nectar-seeking insects, such as bees, beetles, butterflies and ants. In order to be visited by insects, pitcher plants provide a lure prize in the form of nectar produced by flowers (floral nectar) and nectar in other parts outside the flower (extrafloral nectar). In an effort to get the nectar, visitor insects can fall into the hole of the pitcher which will eventually become the food of the pitcher plants.
