Figure 5


Fig. 5. Ground speed in a tunnel with moving axial stripe patterns. Bees flew through a transparent tunnel placed between two conveyor belts that moved the axial stripe pattern at various speeds in the direction of the bees' flight toward the feeder (positive values) or against it (negative values). The data show mean ground speeds ±95% confidence intervals. Five flights were recorded for >20 bees at each belt speed. Moving the axial stripe pattern significantly altered bee ground speeds (ANOVA, F=15.1, d.f.=115, P<0.001).
