Development of eyespot patterns on butterflies - phys.org

WebEyespots are concentric motifs with contrasting colours on butterfly wings. Eyespots have intra- and inter-specific visual signalling functions with adaptive and selective roles. We propose a reaction–diffusion model that accounts for eyespot development. The model considers two diffusive morphogens and three non-diffusive pigment precursors. Web25 aug. 2016 · Butterfly eyespots are complex morphological traits that can vary in size, shape and color composition even on the same wing surface.
