We bought the Protaetia brevitarsis seulensis in Cetoniinae farm, and raised it. We dessect the Protaetia brevitarsis seulensis imago, observed the a secondary wing with SEM(scanning Electron Microscope), and we can observe the structure and thae array of that structure which can infer micro hair. Simulated the model about the turing patterns with jupyter notebook python changing the constant of the equation. After analysis, we judge that pattern is similar to Gray-Scott Model’s equation when F=0.0220, k=0.0610. Hence, our research get the temporary conclusion that gray-scott model contribution the wing’s formation.
