SNK test Cr:

BM = BCM > NJT

SNK test Cr × Or:

BM: Coleoptera = Diptera = Hemiptera = Hymenoptera = Lepidoptera = Orthoptera

BCM: Coleoptera = Diptera = Hemiptera = Hymenoptera = Lepidoptera = Orthoptera

NJT: Hymenoptera = Orthoptera > Lepidoptera > Coleoptera > Hemiptera > Diptera

  1. Differences in the proportion of correct matches provided by three identification criteria (BM: Best Match, BCM: Best Close Match, NJT: Neighbor-Joining Tree) were tested in six insect orders (Coleoptera, Diptera, Hemiptera, Hymenoptera, Lepidoptera, Orthoptera). Before running the analysis, the assumption of homogeneity of variances was verified using Cochran's C-test. SNK tests were used for a posteriori multiple comparisons of means. df: degrees of freedom, MS: mean squares estimates, *** = p < 0.001.
