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.
