Yeah both Camponotus species need hibernation. Only exotic ants (like Camponotus spec. from Malaysia or Laos) can live without hibernation.
and what kind of feed is better for my L.Niger queen without workers, honey or insect??
I've to open the test tube to give her food, can I disturb her???
The queen need both. Honey for her and insects for the protein what is for the eggs.
