They habitually live in bogs and trap and digest insects in their leaves.

Explanation from Wikipedia of the flower of the Sarracenia
…Five sepals superintended by three bracts, numerous anthers and an umbrella-like five-pointed (chamber-forming) style over which five long petals dangle.
The whole flower is held upside down so that the umbrella-like style catches the pollen dropped by anthers.
Bees force themselves into the chamber where there is nectar and much pollen.
Upon exiting the chamber, the bees force their way under one of the flapping petals. This keeps them away from the stigmas, located at the tips of the style, avoiding a self-pollination.
