"After they have eaten everything in their immediate neighbourhood, a single scout sets out to prospect for more. As it explores new parts of the tree, it lays down behind it a trail of scent that exudes from glands on its rear end. This enables it to find its way back to shelter before dawn. The next night, its companions inspect the trail. If it has a single track, as might happen if the caterpillar was taken in the night by some hunter, they will ignore it. But if there is a double track, indicating that the scout returned and if, furthermore, its smell indicates that the scout had a good meal, then the whole colony of several hundred will set off in procession to strip the leaves from yet another part of the fruit tree." (Attenborough 1995:58)
