 The pitchers of "N. attenboroughii" are open to the elements and thus often completely filled with fluid.This fluid is viscous in the lower part of the pitcher and watery above, forming two fractions that do not mix.The upper fraction supports populations of pitcher infauna, particularly mosquito larvae, and the pitchers of this species may benefit from both the usual capture of prey as well as the detritus produced by organisms living within the pitcher fluid.
