Carnivorous plants that have evolved modified leaves known as a pitfall traps – a prey-trapping mechanism featuring a deep cavity filled with liquid. Foraging, flying or crawling insects such as flies are attracted to the cavity formed by the cupped leaf, often by visual lures such as anthocyanin pigments, and nectar bribes. The rim of the pitcher (peristome) is slippery, when moistened by condensation or nectar, causing insects to fall into the trap.
