The “traps” of pitcher plants are actually modified leaves. The flap (or operculum) prevents rain from entering the pitcher. The opening to the pitcher lures insects with nectar, but any bug that reaps the sweet reward will find a very slippery surface. Plop!! Into the digestive fluids at the bottom of the trap.
Many carnivorous plants are threatened or endangered. They live in marshy lands, the kind of places humans drain to build subdivisions and shopping centers. And since marshy areas are low spots in the terrain, chemicals like herbicides can wash from higher ground. People also love carnivorous plants to death – millions of pitcher plants have been dug up and sold to collectors.
What can you do to help the pitcher plants?
1) Support wetlands protection
2) Buy daisies, not carnivorous plants. Even if you buy the plants from a reputable source, it increases demand for these plants.
