Movie 6
Light avoidance of groups of stage 1 and stage 3 larvae
(A) Showing stage 1 larvae moving in a central dark area surrounded by a light annulus of the indicated width (w) for 7 min (5 fold time-lapse). From 26 s onwards, rin and rout and larval trajectories are blended in (Fig. S5A). The flags are set to define rin and rout. Trajectories are boldened after 73 s. Light avoidance is measured in the dark-light border zone (rout - rin).
(B) Likewise showing stage 3 larvae moving in a central dark area surrounded by a light annulus of the indicated width (w) for 7 min (5 fold time-lapse). From 26 s onwards, rin and rout and larval trajectories are blended in (Fig. S5A). The flags are set to define rin and rout. Trajectories are boldened after 73 s. Light avoidance is measured in the dark-light border zone (rout - rin).
