Dinner!

gross!

Evidence suggests that the genus Genlisea has traps specialized to capture protozoa! Meanwhile, Pinguicula and Drosera tend to catch flying insects like gnats, flies, and moths. Pitcher plants (Sarracenia, Nepenthes, Cephalotus, etc.) capture foraging insects, especially flies, moths, wasps, butterflies, beetles, and ants. Venus Flytraps capture any crawling insect---mine feast particularly on spiders, but plants in the wild no doubt have a different diet.

  A few times vertebrates such as rats and birds have been captured. The carnivorous plants in these cases have been Nepenthes, the tropical pitcher plant, but these are rare surprises and do not represent normal prey (any rat or bird that could not struggle, gnaw, or peck its way out of a Nepenthes pitcher is probably sick or near death from other causes). Frogs are more commonly captured, but even this is fairly rare. Nepenthes usually satisfies its gluttonous appetite with crawling bugs and insects. Pass the centipedes, please, I'd like another helping!
