Fig. 7. Velocities and trajectories of six jumps by the same Saldula. (A,C) Three jumps in which the wings were not moved. (A) Velocity, plotted as a three-point rolling average against time, of a point on the body indicated by cross on the cartoon. Peak velocity was reached before take-off. (C) Trajectories of the same three jumps in which vertical movement is plotted against horizontal movement. (B,D) Three jumps in which the wings were moved. (B) Velocity as a three-point rolling average plotted against time. (D) Trajectory.
