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.
First male Bombus campestris of the year on Corstorphine Hill in Edinburgh today. Other six common social bumblebees all recorded also. In garden was B pratorum worker still collecting pollen; probably a second generation of the year.
