Fig. 2. High-speed videographic sequence of an air-evoked escape response performed
by a juvenile wood cricket (N. sylvestris) after being subjected to
the predatory strike simulator (piston, P). Time (T; ms) from the
start of the piston is shown in each frame. (A) A cricket in its resting
position as the piston is approaching from the rear. (B) The cricket enhances
its escape behaviour by a flexion of its hind legs. (C) The cricket starts
jumping (some sand is moved away by the action of hind legs).
