Fig. 4

Recorded way-points with associated relative time stamps. A section (duration, 138 s, blue coloured) of an untrained bumblebees flight trajectory and a flight trajectory (duration, 164 s, red coloured) from the hive () to the feeder () and back, i.e. a foraging bout, of a trained bumblebee is shown on the left (). On the right () a section (duration, 90 s) of a hawkmoth’s flight trajectory of a long term observation flight is shown. Every mark represents one waypoint. Due to the detectors sampling rate approximately 102 waypoints were recorded per second. If no position could be determined, the last known waypoint was taken as the current one. The colour of the marks (i. e. waypoints) displays the relative timestamp. The first waypoint (with relative time stamp zero) is marked with 5% colour intensity, the last waypoint (with relative timestamp one) is marked with 100% color intensity
