Do you know what type of butterwort? How much light is it getting? ARe you using reverse osmosis, distilled, or rain water when you water you plant? I would acclimate the butterwort to reg. inside/outside, where ever its growing humidity, by taking the plastic wrap off a little at a time. is it still new? how long have you had it? it might still be acclimating to its new environment. i would need a little more info to be of more help, sorry

It is a Pinguicula Primofloura, it gets the morning sun in an eastern window, yes im using the right type of water, ive had it 1 week or so, not long.

If it's only been a week, it might be just acclimating to your house.

Is it in direct sunlight? In a terrarium like that direct sunlight might be a bit too much for it...

Yes, if youve only had it for a week its still acclimating, but still i would acclimate it to its own climate without the terrarium for humidity, P. primoflora is a temperate butterwort and will go dormant. heres a link that might help.

Here is a link that might be useful: SNW brief look at p. primoflora
