A view from within the pitcher of this semi-carnivorous plant (Nepenthes ampullaria). Without a protective lid as in most other species of Nepenthes, the pitchers of N. ampullaria are exposed to rain as well as a continual fall of leaf litter from the forest canopy. In this way they are able to derive a significant portion of their nutrients from detritus. The dark objects on the inner rim are pupae of a Megaselia fly whose larvae feed on dead insects within the pitcher fluid. Sarawak, Malaysia.
