Outline of Final Research Achievements

It was demonstrated that the color learning of the butterfly is faster on the flowers with scent than on the flowers without scent. In other words, as in the case of bumblebee, it was demonstrated that "the scent of flowers promotes color learning of flowers in butterflies.
Next, when the butterflies learned both the color and the scent of flowers, they did not give priority to using either color or scent information. That is, information on learned color and odor is considered to be equally important in Peris rapae butterfly.
