Swarm of bees in a tree in the yard, earlier this summer. This is only the third time I have seen a swarm. I got close to snap this picture, because I have heard that swarming bees are not aggressive. If they noticed me, I couldn’t tell.
I looked up swarming bees on Wikipedia. When a hive becomes large enough to make new queens, the old Queen leaves with about 60% of the worker bees. They spend a few days scouting out new locations for their hive.
I thought about trying to capture the swarm in a box, and starting my own apiary. By the time I worked up my courage, they had flown away.
