Figure 1. Averaged image of Drosophila melanogaster tra2 female wing. The red circles indicate the numbered locations of the thirteen landmarks used in this study.  They represent the intersections of the major veins (I-VI) with each other, crossveins and the wing margin.  Fifteen wings were superimposed and averaged using the programs tpsDig and tpsSuper of Rohlf (1997).
