The Nepenthes are a carnivorous plant genre belonging to the Nepenthaceae, also known as “tropical jar-plants” or “monkey cups”, which come from the fact that there have been seen animals drinking the rainwater that collects itself inside this plants. Their jar-like shape is due to the development of the middle vein of the leaf.The Nepenthes species trap and kill their preys in a passive way, mainly just extracting the nitrogen and phosphorus from their bodies for feeding themselves and complete their necessary nutrition for their growing. Like most carnivorous plants they use nectar secretions and bright coloring for attracting insects of all kinds. Their most frequent preys are ants, spiders, scorpions, etc.
