Just picked up on this thread..... commiserations on the loss.
A beekeeper of my acquaintance had a colony disappear out of an orchard near the Birches a while back. His hive and super colours are contrasting and quite distinctive so he could easily have identified them. He reported the theft to the police and since it was an unusual crime for the area, the Portadown Times picked up on it. Shortly after that the hive made its own way back to his orchard and it had even managed to find itself a whole new super.
The colour of that "new" super gave a good suggestion as to where the colony had been vacationing.....
It might be profitable to get a story run on the theft.
