summary | Previous studies have established that foraging bees control their flight by making extensive use of optic flow: the apparent motion in the visual scene generated by their own movement. However, the use of real physical objects in such studies limits the scope for manipulating cues experimentally to identify how the bees utilise sensory information. Here we implement a closed-loop tracking system that allows us to modulate visual stimuli in real-time based on the bee's movements, thus creating the illusion of virtual objects in a 3D space. We trained individual bumblebees, Bombus ignitus, to feed from a static target displayed on the floor of a flight arena, and then observed their responses to various virtual objects when they returned to forage. Finally, we challenged the bees with physically impossible ambiguous stimuli, which give conflicting motion and occlusion cues. In such cases, they behaved in accordance with the motion information, seemingly ignoring occlusion. |
