Colour polymorphic lures exploit innate preferences for spectral versus luminance cues in dipteran prey

Table 3 Summary of a-posteriori simultaneous tests for homogeneity, from experiment 4 in which flies were offered the simultaneous choice of yellow or white-banded spider models, presented versus an “augmented” background

Visual angle describes the apparent size of model spiders as viewed by flies at the choice point in a Y-maze apparatus (Additional file 1: Figure S1)
Asterisks indicate significant heterogeneity within a set, with maximally non-significant sets immediately above
