Fig. 5. Images of a jump by Cephalelus viewed from the side and captured at 5000 s^–1 and each with an exposure time of 0.03 ms. The first movement of a hind leg occurred 2 ms before take-off (arrow). The front and middle legs (arrows) lost contact with the ground before take-off. After take-off the body began to rotate around its longitudinal axis. The lines on the first frame (–2.2 ms) indicate how the angle between the head and the pronotum was measured.
