The harvesting of the ant queens (as well as the competition for resources with more aggressive species of leafcutter-ants/"''arrieras''") causes a progressive decrease of the ant populations, as estimated in recent studies;Santamaria ''et al.'' 2005 according to observations, only a sixth of the ant population of twelve years ago exists today, and for this reason, there is concern about the species' future.
