They are very primitive ants, grow fungus but use various things like caterpillar droppings, dead leaves, bits or stem etc. I am sure they would be more difficult to keep than Atta or Acro. Not sure if anyone currently keeps them or has ever seen them. Maybe their husbandry is exclusive to academic institutes where they are being studied. Interested in your thoughts, Andrew
