pheromones. The swarm halts upon reaching the nest site, whereu¬ 
pon more scouts drop out of the swarm cloud and begin releasing 
assembly pheromones at the nest entrance to help pinpoint its loca¬ 
tion. During the next 20 min the bees flood into the nest cavity and 
so complete the swift, clean process of warm movement.
