Color-coded comparisons of Trithemis forewing and hindwing mean shapes illustrating which wing pixels changed their brightness values least (blue) and most (red) along the linear discriminant vectors separating landscape (left) and water-body (right) species. As with the previous landmark-semilandmark results, the transitions from forested to open landscape habitats and temporary-standing and running water-body habitats involve essentially identical shape transitions, despite different species cohorts being placed into these habitat groups. Note that the forewing and hindwing areas exhibiting the greatest changes in pixel brightness values constitute either very small well specified regions (forewings) or large areas (hindwings) that were either not included in the landmark-semilandmark sampling scheme (forewings) or could not be so included owing to the fact that the wing character most consistent with between-group difference was a pigmentation region (hindwings)
