For females, only eight of the 18 parameters could be used for the PCA. These parameters are CLP, FL1, FL2, HL, HW, MSW, MTW, and OOD. All other parameters were eliminated because of insufficient correlation values (p> 0.05%). Andrena cyanomicans and A. mirna show a clearly separated clustering. The value of the explained variance of the first axis is high (69.4%). In males, only six parameters could be used (FL1, FL2, FL3, HL, HW, OOD). The three species are not clearly separated from each other in males (two males in marginal positions). The value of the explained variance of the first axis is high (68.8%). The influence of the parameters corresponds to that of the females.
