Carnivorous Plant Growers

I have some of questions for those who grow Pinguiculas.

I picked up a little Pirouette a few weeks ago. Seems to be doing ok, nice green color, roots looked like a bundle of fine filaments when I potted it up in peat moss/perlite mix. Can't really tell if he's grown any or at all.

So, this little guy hasn't caught anything but dust. I get a gnat a day but I have to swat them. I think he's sticky enough, I inadvertently picked him up.

So my questions are:

Is it the nature of Pirouettes not to be good gnat catchers?
How do you keep these dusted/clean?
How do you feed them if not bugs (I've feed them along with my chids)?
