Tethered Apple Fly (IMAGE) Proceedings of the National Academy of Sciences Caption A tethered apple fly (Rhagoletis pomonella) approaching a tree-like virtual object in a multimodal virtual reality arena. Computer monitors provide a visual panorama and glass capillaries provide 360º wind and odor cues. Flies can distinguish the size and distance of virtual objects amidst a complex background and incorporate directional airflow and odor to navigate towards distant targets.
