Although beetles use their hind wings for flight, some recent studies have shown that the elytra, through their rotation angle and wing locking systems indirectly affect the ability of beetles to fly, and further influence the aerodynamic performance and the effort for the production of vertical force during flight, The color mechanism of reversible and irreversible color-changing beetle, and biomimetic coupling mechanism of color-tunable composite material, flight mechanism of deployable hindwings of beetle and biomimetic, In this paper, a classification of phenomenologically symmetric geometries of two sets of rank (n + 1,m) with n > 2 and m > 3 is constructed by the method of embedding.
