Phylomorphospace plots for the subspaces formed by the first two Procrustes principal components calculated from the Trithemis forewing and hindwing landmark-semilandmark datasets. Projected positions of the Trithemis (tree tip) species color coded to reflect their landscape and water body habitat preferences. Note the number of tree branches that cross one another in this space, indicating that the distribution of wing shapes is not being controlled, or reflecting phylogenetic structure to any substantial extent. These results support the findings of the statistical phylogenetic signal test (Kmult) shown in Fig. 3
