Another team of researchers led by Geng Li investigated the influence of the ant group's density on the symmetry breaking. They used the red imported fire ant to repeat the experiment with different amounts of ants. The results show that symmetry breaking is high at low densities of ants, but decreases beyond a certain point in the density of ants. In other words, when density is low, the ant group produces a collective escaping behavior, while at high density, their behavior is more like random particles.
