Flightpath Overlay Avoidance (IMAGE) University of Minnesota Caption Robber flies operate at speeds the human eye simply cannot process. Researchers used stereo, high-speed videography (at 1000 fps) to record the animal’s interceptive flight path. This overlay image shows the fly continuing to the left to get more clearance against the acetate obstacle. Video available upon request.
