Figure 4 from: Ren J, Bai M, Yang X-K, Zhang R-Z, Ge S-Q (2017) Geometric morphometrics analysis of the hind wing of leaf beetles: proximal and distal parts are separate modules. ZooKeys 685: 131-149. https://doi.org/10.3897/zookeys.685.13084
Figure 4 - Modularity test results. A The hypothesized partition: proximal part landmarks 1-6, 23, 24, and 26–36 and distal part landmarks 7–22, 25; different colour presents different modules B The partition with minimal covariance in all evaluated 104 partitions by RV coefficient C The partition with minimal covariance in all evaluated 106 partitions by RV coefficient.

Figure 2 - PCA and CVA results. A Centroid size graph of hind wing landmarks (Procrustes fit) B PCA results, the shape changes associated with the first three PCs: the relative size of the apical area which could be considered the main feature (variance contribution ratio was 45.01%) to influence of the overall variance of the hind wing, the changes of cross vein cv in the middle area (variance contribution ratio was 12.39%), and relative size of the anal area size (variance contribution ratio was 10.56%) C CVA results, the axis of CV1 and CV2 presented the first two large shape variance of all variance; points with different colours indicated different subtribes' specimens; the ellipse is presented as an equal-frequency ellipse with a given probability level of 90%, which contains approximately 90% of the data points.

Figure 1 - Leaf beetle hind wing (Chrysomela populi Linnaeus), with landmark locations (the dot with number), vein nomenclature and regional division. The nomenclature of the wing venation follows that of Kukalová-Peck & Lawrence (1993, 2004). Radial area: green, central area: blue, medial area: purple, anal area: yellow, apical (folding) area: red. Proximal part landmarks 1–6, 23, 24, and 26–36 mainly include radial, medial, and anal areas; distal part landmarks 7–22 and 25 include the central area, radial cell, and apical area. Abbreviations: Costa (C), Subcosta (Sc), Subcosta Anterior (ScA), Subcosta Posterior (ScP), Radius Anterior (RA), Radius Posterior (RP), Radial cross veins (r3, r4), Media Posterior (MP), Radio-medial cross veins (rp-mp1, rp-mp2), medial cross vein (cv), Cubitus Anterior (CuA), Medio-cubital Cross-vein or Arculus (mp-cua), Anal Anterior (AA), Anal posterior (AP). "+" indicates fused veins. The sub-number of veins reflects vein branches.

Figure 3 - PLS analysis results. A Scatter plot of the PLS1 of two blocks B Shape changes associated with the first PLS axes of two blocks: each diagram shows the block change along the PLS1 in the positive or negative direction, corresponding to Figure 3A.
