a passive trap, pitfall traps attract prey with nectar bribes secreted by the peristome and bright flower-like anthocyanin patterning within the pitcher. the linings of most pitcher plants are covered in a loose coating of waxy flakes which are slippery for insects, causing them to fall into the pitcher. once within the pitcher structure, digestive enzymes or mutualistic species break down the prey into an absorbable form for the plant. water can become trapped within the pitcher, making a habitat for other flora and fauna. this type of 'water body' is called a phytotelma.
