David Cramp is an expert on bees and bee science and has pioneered the use of drones and digital mapping technology in aspects of bee research.
He's now set to share his gift in Tonga as a beekeeping advisor for the government. He has also written a number of books on bees.
His latest, The Honey Bee, is a definitive guide to the insect and its exploits. In it, he breaks down the mysteries of life in the hive: how a Queen is formed, the role and rank of different bees in the colony, the relationship between bees and flowers, why bees swarm, and the importance of pollination.
