Just a thought that came into my mind. Could it be that the pitchers are bigger because the plant has been deprived of nutrients from insect prey since the previous pitcher has been broken off. I have experienced many times with my plants that when I starve the pitchers, the plant will produce more pitchers and bigger ones in the new leaves. Sometime even cause older leaves to produce picthers if the growing tips has not turned black or dried out. Perhaps the same theory works here. When a pitcher is broken, it is starved of nutrients, so it produces a bigger pitcher to compensate or to survive because it's life might be threathen.

If so, I wonder whether it would work the same if we just starve the pitchers of food. That way we keep the small older picthers as well as the new bigger pitchers. What do you guys/gals think?
