Fig. 9. A backward jump by a nymph from an initial vertical posture. Selected
frames from the sequence in which take-off occurred at 0 ms are arranged in
two columns. The position of the head and the tip of the abdomen and the
distance of the body from the vertical pillar are plotted in the bottom two
frames. The abdomen is flicked forwards and the body moves upwards before the
legs lose contact with the pillar and the insect falls in a trajectory away
from the pillar.
