  1. I wonder if those huge “jars” full of liquid could do anything with polarized light? Many insect can detect certain surfaces due to the polarization of it. If there is a watery surface inside an open pitcher of the plant is producing water-like polarization on that location – how would this correlate with its trapping success? I mean some insects might have learned how to recognize these traps despite all other attractive features of it.
    About 20 years ago I had a Nepenthes alata, I loved to look into the pitchers each day searching for an insect fallen into the traps. But mostly I had to catch some flies outside my flat for feeding the plant because there was not too much inside.
