Carnivorous Plants: Another ping - and questions, 1 by Keyring

This is my very first ping - given to me as a rootless pup and a "probably primuliflora" tag. A few questions....

Can the pup be left attached for ever? or is it best to cut it off at some point?

Leaf color - do they get more pink with more light? Are these a bit too pink? (ie stressed?)

Leaf type - does this kind have the same type of leaves year round? or should I have different leaves in the winter? (This one had a short "winter" a few weeks ago and we are kinda into spring at my place now....)

And you can see no bugs :-( Well, I suppose it's good that I have no fungus gnats flying around but.... I'm assuming it will be fine without food for a few months?
