Euclidean resemblance matrix based on cuticular hydrocarbon profiles of queens (Q; left side) and workers (W; right side) from the four species of Temnothorax ants involved in the mixed-species experiment (Tn = T. nylanderi, Tc = T. crassispinus, Tu = T. unifasciatus, Tr = T. recedens). Figures in bold indicate a close Euclidean Distance between a pair of groups in contrast to the other compared pairs of groups.
