Fig. 3. Sequential mages of a jump by Graphocephala viewed from the side, captured at 4000 frames s^–1 and each with an exposure time of 0.125 ms. (A) The first movement of a hind leg occurred 5.75 ms before take-off. (B) The continuing backwards movement of the femur and extension of the tibia raised the body from the ground so that first the middle legs and then the front legs lost contact with the ground. (C) Take-off was achieved when the hind legs were close to full extension. Scale bar, 2 mm.
