Mystery Brown Spots on Nepenthes: Virus or Insect?

Jan has brown spots on Nepenthes (photo). Can't reply on old thread. Asks for diagnosis.

Expert Assessment

Jeff Dallas: Spots resemble N. rafflesiana natural spots (not problematic) but could be insect vectoring fungus. Try systemic insecticide+fungicide (Bayer 3-in-1). If no change in a month, likely virus—isolate plant. Also recommends ProBoards forum for top Nepenthes experts.

Good Growing!
