Many male Bombus sylvestris “hilltopping” on Traprain Law, East Lothian. At one stage there were 3 males in a mating scrum with a mite-carrying queen. The queen eventually fought off the males and appeared to be trying to burrow into some dry moss to escape further attention. However she was found by a couple of males and, after further struggles, flew off without being mated. All this took place over 20 minutes around midday today.
