Fig 1.
Length and area measurements taken for each analysed wing photograph.
These measures were used for methods 1 and 2.
Fig 2.
Landmarks used to generate data for methods 3 and 4.
All landmarks were used in the geometric morphometric approach (method 4). Arrows show the linear distances that were taken for method 3.

Cross-validated correct classification rates using traditional and geometric morphometrics.
Fig 3.
Between-group principal component analysis and average species shapes.
Scatterplot of the scores along the first two between-group principal components. Overlaid, predicted shape changes along the first between-group principal component and average shape of each species. Points in the scatterplot are color-coded as the average shapes. In the plots of average species shape, the grand average shape is depicted in grey.
