Table 1 Background matching and disruptive coloration of praying mantis of different morphospecies against trunk backgrounds in the southern Amazon rainforest. Summary results of the analysis of variance applied to linear mixed-effects models testing differences in colour and luminance contrasts (as JNDs—just-noticeable differences) and edge disruption (as GabRat) based on the vision of the blue tit (Cyanistes caeruleus) between different trunk backgrounds. For all models, mantis identity was included as a random factor to control for repeated measurements made in the same individual. Significant differences are shown in bold.
