A cluster of butterflies with eyespots on their wings fly away in the sky with concentric circles. Looking carefully, they consist of individuals with wild-type eyespots and mutants with different patterns than the wild-type. There are various theories about the mechanism of forming eyespots. One of them is that it involves the concentric diffusion of a morphogen from the center, but it has recently begun to be questioned. We thank Dr. Shigeyuki Koshikawa (Graduate School of Environmental Science, Hokkaido University) for providing us an idea of drawing and the current status of research in this field.
