The Principal Components Analysis (PCA) of individuals of both studied species (CP: C. polyacantha site, CR: C. rudis site)—differentiation across morphological characteristics. The roman numbers mean the months of study. Dashed grey line defines the approximate limit of morphological variability of the species.
