Variation in mean waggle duration (black bars) and the mean pure waggle duration (white bars) of bees after flying in a tunnel with different surfaces providing optic flow (random Julesz pattern) or no optic flow (axial stripes) (indicated below). Controls, behaviour after outdoor flight to the tunnel entrance; see text for details. Other details as in Fig. 1.
