Within the last three years, at two different houses, in two different states, I've had a swarm of bee temporarily set up home in a tree in the front yard.
First time was in Texas.
Second time was this afternoon. I was outside spreading mulch and heard a loud buzzing sound. When I looked up, bees were everywhere. They decided to stop for rest. I hope they decide to leave soon.
Here is a short video of them.
I think they're following me.
