Fig. 9

Monarch (or milkweed) butterfly (Danaus plexippus) vs. Wild boar (Sus scrofa); \(n =\) 315; Kuiper’s statistic is \(0.1292 / \sigma = 2.294\), Kolmogorov’s and Smirnov’s is \(0.1292 / \sigma = 2.294\); the reliability diagrams with 30 bins or less (b, c, d, and e) underestimate (or fail to resolve) the extreme deviation at the lowest scores, whereas the diagrams with 50 bins (f and g) are far too noisy for the other scores. The graph of cumulative differences (a) resolves all these behaviors clearly. The metrics of Kuiper and of Kolmogorov and Smirnov both report somewhat statistically significant deviations between the subpopulations, though much less extreme than in Figs. 7 and 8
