Well, I think established plants here flower yearly. N. khasiana, for
example, seemed to flower each spring/early summer where I have seen it
bloom. Since it seems to be season sensitive, it probably is back home.
Plants in the wild usually do not flower indiscriminately, and a
dioecious plant would not be able to afford to.

As for pollinators - considering that most of the Nepenthes flowers smell
very much like mouse urine, I would bet the pollinator would be a fly/flies.
