Movie 1

Spatial distribution of 40 L. sericata larvae over time. The arena included small spots containing fresh (right) and rotten liver (left). The movie is a time-lapse showing 30 pictures per second, where each picture is a photo taken every two minutes (i.e., one second on the movie corresponds to one hour of experiment). From 38 h to 48 h, larvae regularly switched from one spot to the other.
