Scatter plot generated with R 4.0 software (implemented by the package adegenet 2.1.3) representing principal component analysis (PCA) of 266 mites from wild herbivores deriving from ten different geographical origins. Variance is explained by 12.4 and 5.5% of components 1 and 2, respectively. The eigenvalues of the two axes are displayed in the bar plot on the left. Label names refer to the origin of host species (see Table 1). Colors (on the red-blue-green scale) and distances display the genetic diversity
