This species of orchid traps in-
                                                         sects that can fertilize it, for
                                                       short periods, but soon releases
                                                         them. These insects are used
                                                            solely for fertilization.







































              Dischidia rafflesiana (above) attracts ants, but is not carnivorous. Its pitcher-
              shaped leaves serve the ants as a nest. It feeds the ants and uses the nitrogen
              obtained from their wastes as a nutrient. The Pinguicula (butterwort) has leaves
              with sticky, slippery surfaces. It traps insects landing on it with a viscous secre-
              tion, in which enzymes allow the insect to be broken down and digested.
