Abstract: Statistical analysis of 11 math-morphological feature (MMF) (such as area, perimeter, etc.) from images of 23 species of insects of the Pentatomidae, Coreidae, Noctuidae, Saturniidae, Pieridae, Melolonthidae Rutelidae and Cerambycidae families indicates that the ranked reliability of MMF in the identification of insect families is, from high to low: (roundness, eccentricity)>(area, perimeter, X-length, sphericity)>(Y-length, circularity)>(form factor, lobation)>hole number. From the perspective of mathematical morphology, the kinship between the Nuctuidae, Saturniidae and Pieridae can be ranked as follows: Nuctuidae and Pieridae> Saturniidae and Pieridae> Nuctuidae and Saturniidae. Kinship between the Melolonthidae, Rutelidae and Cerambycidae can be ranked as follows: Melolonthidae and Cerambycidae> Rutelidae and Cerambycidae> Melolonthidae and Rutelidae.
