). Action of the pump is revealed by inward movement of the dorsal cornua and there is one pumping action per lunge (Film 3). The head skeleton is fixed and does not protract or retract (Film 4). The dorsal plates are inflexible and do not fold during locomotion, but raise and lower in relation to the position of the peristaltic movement wave. Direction changes are due to the front compartment pressing against the substrate at an angle relative to the previous position. Alternatively, S-shaped, sideways motion occurs. With the anal segment and the pseudocephalon gripping the substrate, opposing contraction/expansion of the lateral margins of the first few abdominal segments presses one side against the substrate while the other expands, lifts and lowers. When the expanded side touches the substrate, inducing a characteristic rocking motion, the prothorax and pseudocephalon move to a position lateral to the start position and by repetition of these movements, the body shifts sideways (Film 2). This larva is unable to make sharp changes in direction, twist round and it avoids moving on narrow substrates, such as leaf petioles. It is, however, able to squeeze through spaces less than its height, such as between wet, overlapping leaves.
