Fig. 8 Boxplots comparing selected traits among the four proposed ecomorphs. PC1 refers to the first principal component resulting from the PCA analysis. It mainly describes the gradient from slender bodies with long antennae (negative values) to stout bodies with short antennae (positive values). All traits except body length and PC1 values are presented relative to total body length
