Fig.23 in A taxonomic revision of the Palaearctic members of the Formica rufa group (Hymenoptera: Formicidae) - the famous mound-building red wood ants

Fig.23: Linear discriminant analysis of 169 samples of workers of Formica rufa (white rhombs), Formica polyctena × rufa and backcrosses (black squares), and F. polyctena (white dots) considering 12 morphological characters. The missing gaps between the clusters indicate introgression and prevent a clear discrimination of hybrids from parental species. Note that the frequency of hybrids in the analysis is about fivefold larger than expected for random sampling all over Europe.
