For those who don't know, carnivorous plants attract, capture, and digest insects for food. Most grow in areas such as swamps, sphagnum bogs, etc. Some trap insects in fluid filled pitchers. Others have sticky leaves which adhere to and goop up their victims. The infamous venus fly trap folds around it's prey and some even use suction to pull tiny animals into bladders. Very cool stuff.
Of all my plants, my prized possesion was a pitcher plant (Nepenthes,) that I held on to for about 2 years. She got huge - I'd say maybe 4ft. by 5ft. with about 150 or so pitchers (itty bitty babies included.) Sadly, she withered away and died.
Below are pics of her species followed by other carnivorous plants.

To care for these, each pitcher must constantly hold about 1/3 of water at all times (this involves checking each pitcher and filling with water on a daily basis.) It then turns to a sweet fluid that attracts insects. They're lured inside and drown in the water, dissolving over time as the plant uses the insects for nutrients.
