Abstract: Statistical analyses of 11 math morphological features (MMF) (such as area, perimeter, etc.) from images of 23 species of insects from the Lepidopter a and Coleoptera families Noctuoidea, Bombycoidea, Papilionoidea, Scarabaeoidea and Chrysomeloidea indicates that the ranked reliability of MMF in the identification of insect superfamilies is, from high to low: circularity>(area, perimeter, X-length, sphericity, roundness, eccentricity)>(Ylength, lobation)>(form factor, hole number). From the perspective of mathematical morphology, the kinship of three superfamilies can be ranked as follows: Noctuoidea & Papilionoidea>Bombycoidea & Papilionoidea>Noctuoidea & Bombycoidea.

Key words: Mathmorphological feature(MMF), insect classification, computer vision technology, superfamily
