  Termites form complex dynamical trail networks from simple individual rules
when exploring their environment. To help identify those simple rules, we
reconstructed trail networks from time-lapse images of roaming termites. We
quantified the trails' frequentations over time and compared them to the ones
obtained by a null model. Arena borders were preferred in both simulated and
observed data. Yet, the amplification phenomenon was higher with real termites,
underlining the role of pheromones.
