+Antlions organize themselves systematically in response to the
+environments where they find themselves.
+Individuals attempt to regularize their own pit locations according to
+nearby pits and the borders of the living space, and this structure is
+affirmed by a statistical test on the uniformity of their distribution.
+Using a Monte Carlo simulation of 10,000 randomly distributed patterns
+of the same number of pits as observed from each trial, a typical
+distribution of the distance to the nearest neighbor was determined.
+The distance to the nearest neighbor is approximately independent for
+each pit, so a Cram\'er-von Mises statistical test was applied to the
+observed distributions, resulting in striking evidence that these pit%'
+dsitributions do not conform to a uniformly random independent
+distribution of each pit, with all (except one) distributions of
+antlions having $p<0.05.$
