I have several Peace Lilies that we\'re doing quite well and one day I noticed all the tops gone, as if someone came through with cutters and sawed off the leaves, which is impossible given their location. I can\'t figure out what bug would do this. The plants that aren\'t severely damaged don\'t have any tell tale signs of slug infestation. It\'s still early spring, so maybe caterpillars. I\'m very upset and not sure if they\'ll come back. Need help identifying the bug and help restoring my plants.
