While sitting outside this afternoon my attention was caught by an
intense buzzing sound. Looking up I saw a cloud around 50 feet diameter
and twenty feet off the ground move close to our house then drift off
over the lawn then it moved off into the distance across a field. The
cloud must have consisted of thousands of buzzing individuals. I
couldn't see what insect it was - it was literally a huge buzzing cloud
of dots. Bees or what? I've never seen anything like it in my life in
all my years of rural living. I didn't think bees made such huge swarm
clouds?

Sounds like a large primary swarm of bees. Bear in mind that June is
the month when bees are most likely to swarm, and a large colony may
contain some 50,000 bees half of which may debunk in the first
(primary) swarm.


So it was bees then! I wouldn't have liked to be in the middle of that
cloud, it looked quite intimidating!
