A) Time course of two LDCs from a flight segment of 2000 wingbeat cycles. B) Recorded stroke trajectories of 10 cycles (highlighted in A). Red: left wing; blue: right wing. Black line shows mean trajectory during the whole flight segment. C, D) Reconstructed stroke trajectories of the same 10 cycles with variances of all components but Comp-I (in C) or Comp-II (in D) suppressed. The left-right antisymmetric variation in C corresponds aerodynamically to a yaw saccade maneuver, and the symmetric variation in D to a lift maneuver.
