Most species being found only in the southeast states. It is also the first plant with a pitfall trap that we will look at. This is the most common example.

The plant’s leaves have evolved into a funnel, with a hood like structure growing over the opening to prevent rain water from diluting the digestive juices.

This is a perfect example of a trap for any carnivorous plants out there.. Insects are attracted by colour, smell and a nectar-like secretion on the lip of the pitcher.

Slippery footings, aided in at least one species, by a narcotic drug lacing the nectar, causes insects to fall inside where they die and are digested by proteases and other enzymes
