Drone to drone
When I was trying to establish the size of the Greenham Common Drone Congregation Area (DCA – those special sites where honeybee drones gather in the hope of mating with a queen), I met a couple flying a radio-controlled drone.
In conversation, they told me that they had noticed some insects flying around their drone. I was obviously intrigued – all the more so when they told me that their drone had a video camera onboard. They have sent me this video:

The insects must be honeybee drones attracted by the movement. Honeybee drones will even chase after pebbles thrown in the air in a DCA, so despite the fact that the radio-controlled drone is rather unlike a queen, their excitement clearly gets the better of them!
This finding becomes more intriguing when you realise the radio-controlled drone is flying at somewhere between 10 and 20 metres. I find drones at just three metres above the ground. If I raise the fishing rod lure to five metres, the result is no better and, if anything, it doesn’t attract so many drones.
Could the drones be flying at two different bands of heights or are they spread evenly in height above ground?
Earlier research (Koeniger et al, 1989) observed that Italian drones were most abundant at four metres above the ground, while Carniolan drones were more abundant at 2o metres. Koeniger thought these characteristics were inherited and that Italian queens were more likely to mate with Italian queens and vice-versa.
As a result of the radio-controlled finding, I have put out a call to drone-flyers to see if they have had similar experiences. Already I have had a report of one drone being «swamped by bees» on the famous Hampstead Heath, a parkland hill in North London.
