Fig. 6 in Patterns of acoustic and morphometric variation in species of genus Tettigettalna (Hemiptera: Cicadidae): Sympatric populations show unexpected differences

Fig. 6. Scatter plot of the 69 Tettigettalna argentata and Tettigettalna mariae occurring allopatrically (Allo) and sympatrically (Sym) in the first two PCA components extracted from a correlation matrix composed of 13 acoustic variables. See ST3 for details of the Eigen analysis and factor loadings.
