Innate colour preference of intact individuals in different ambient odour conditions; (a) no particular plant scent (control), (b) floral scent, (c) larval host plants, (d) synthetic mimics and (e) innate colour preference with host plants in individuals whose antennae were blocked with mascara. White asterisks indicate significant differences in proportion of visits to each colour between the odourless (control) and various plant scent conditions (Fisher's exact test; *p < 0.05, **p < 0.001). Black asterisks on the left show between-sex comparisons of the distribution of visits over all four colours (Fisher's exact test; *p < 0.05, **p < 0.001). Numbers on the right side indicate numbers of tested individuals.
