Fly Speed Tests
Sam Fabian, a doctoral student at the University of Cambridge, readies the "fly teaser" for a high-speed video shoot of robber fly antics. The researchers filmed flies attacking silver beads on a fishing line, which were moved in pre-ordained directions by motors and pulleys. From these videos, they could reconstruct three-dimensional models of the flies' flight trajectory.
