Freezing and Escape in Response to An Overhead Shadow (VIDEO)
Caption
A single fly walks back and forth, and briefly grooms, before a shadow moves overhead. The fly jumps and freezes in place, its wings and other appendages held motionless. After about 5 seconds, the fly suddenly breaks its freezing posture, and escapes.
