Single track

Like ants and termites, bees too are
known to follow a fixed path whenever they are on the move.
Entomologists S A Cameron and J B
Whitfield studied the Bombus tranversalis species of humble bee in the
Amazonian rainforests. Worker
bees - in order to obtain material
to build a canopy for their colony -
moved along a path cleared by
them. At the end of each path, a
thick mat of fallen leaves was
spotted. On dropping leaves and
twigs along the trail, the scientists
found that the bees cleared them
away in no time.
