Also known as monkey cups, this plant is primarily found in the tropical regions of Asia. It also belongs to the family of pitcher plants, but what makes it different is its availability in the tropics. This plant first produces tiny buds that later develop into pitcher-shaped leaves carrying nectar glands and a sticky sap to invite and drown the bugs, respectively. Once inside the pitcher, the bugs find it impossible to crawl upwards due to the presence of the sap produced internally by the plant.

Insect larvae feed on the leftovers found inside the cups of these plants.
