Antennae Help Flies ‘Cruise’ In Gusty Winds

A tracing of the flies' flight trajectories as they explore in a wind tunnel, as seen from above. Each observation by the cameras is scaled according to flight speed, as if the animal was dribbling paint as it was flying; the longer the residence time, the larger the dot. Each trajectory is shown in a different color. The stars indicate when the flies were subjected to a brief gust of wind. These experiments revealed how the wind-sensing antennae stabilize the fly's visual flight controller.Antennae Help Flies ‘Cruise’ In Gusty Winds
