Yeah don't repot it for a while and if you do don't expose the roots (very sensitive)
Then wait until it gets bone dry and then I water it again.
It looks very wet to me...
When you water, water around the perimeter of the pot and not near the crown which can lead to rot.
Too wet. My Cephalotus is on a slight hill, and I water in the "moat" around it (which, over time, makes it a little deeper, I've been doing it for 1.5 years, it USED to be level with the Cephalotus but now it's a slight hill). I simply put the pot to the sink, turn the cool water on, wait for it to flood a little and go into the soil. Done! Then wait until it gets bone dry and then I water it again. Be careful, don't fertilize, uh... I'm really only experienced with the smaller ones but not baby like that one. I got mine when it JUST moved from baby pitchers to small adult pitchers.
I've never seen any... Maybe it is being kept too wet as others above have suggested. Just let it dry out more between waterings. Probably fungus gnats.
xvart, thanks for the photo. A picture speaks a thousand words.
Most growers would have thrown out the plant, not knowing that it could possibly regenerate from the rhizome.
