Another interpretation is that, upon entering a shaded area, the younger larvae exhibit a "shadow response"--a photokinetic response that changes the level of activity rather than the direction of movement.
On the basis of the overt responses of the long posterior cilia to abrupt changes in light intensity, and the asymmetric response of the long posterior cilia to light shining on the cilia from the side, as shown in Figure 5, we hypothesize that the larva steers by the subtle photokinetic responses of each ciliated cell to the light, as diagrammed in Figure 10.
