My research interest is how beautiful swallowtail butterflies, Papilio xuthus, see this world in terms of their visual perception and neural mechanism. So far I have focused on this flower-visiting behavior of the butterflies and clarified their visual abilities through physiological-behavioral experiments. Then my team found that their perceptual world is more sophisticated than our expectation. In especially I amazed that they can discriminate only one nm-difference as different colors at three wavelength regions, and e-vector angle of polarized light as different brightness. These their visual abilities must be represented in their tiny brain of approximately 1 mm³. We are therefore conducting various neurophysiological experiment to investigate how visual information is processed in a such small brain. In the future, I would like to expand my research to understanding the coevolution of different organisms by interpreting the relationship between the perceptual world of Lepidopteran insects and the various characteristics of flowers from both neurobehavioral and behavioral ecology perspectives.
