| Research Abstract |
We studied neural basis of color vision using butterflies as the model system. Comparative studies revealed that (1) the photoreceptor spectral sensitivities are often sexually dimorphic, and (2) the degree of rhabdom tiering is quite diverse among species. The analysis of Papilio visual system revealed that (3) foraging Papilio detect the target edge using brightness contrast upon landing, and that (4) the interphotoreceptor connections may be inhibitory.
