Fig. 2From: Drosophila pachea asymmetric lobes are part of a grasping device and stabilize one-sided matingMating angle and tilting index are affected by left lobe ablation and by laser removal of left lobe bristles. Shown are time series of mating angle (a, c, e) and tilting index (b, d, f) in mating couples with control unmodified control males (a, b), “left lobe cut” males (c, d) and “left lobe shaved” males (e, f). Measurements from the same couple are connected by a black line. No measurements were taken if the female could not be observed from exactly above, so the length of a time series does not necessarily represent mating durationBack to article page
