from what i heard and what u said,i think its the "Thrips".they're not fatal but from what i heard,it sucks the juice from the pitcher(sarrs or neps) and the pitcher will loose their colour and turn almost pale whittish if the infection is TOO long.well i dont know hw to get rid of it but u can take weeps's suggestion.
sry if somebody thinks im bossying around but this is what i heard.
this is where i know about this.
