Reconstructed dipping flight in host odour. Cumulative horizontal displacement flown per 20 ms intervals against height (mean ± standard error, s.e.), based on data from n = 84 peaks and n = 82 troughs (taken from 25 tracks) and a calculated trough-trough period of ~0.5 s. Square indicates minima of trough or maxima of peak, to which each track segment was aligned. Small error bars leading into and out of trough show highly consistent ground speed and flight angle to ground of tracks, whereas there is greater variation between tracks in flight trajectories of peaks
