A swarm of bees in May is worth a load of hay;
A swarm of bees in June is worth a silver spoon;
A swarm of bees in July is not worth a fly.
I have been working in the yard a lot lately. On Sunday, I figure I deserve a little break so off I go to drink a pint. Then, I get a phone call from Phil.
“We have a bee problem,” he informs me. Gasp! A branch laying on the lawn is absolutely covered with bees. It seems that the honey bees from the Big Tree are swarming!
“Take pictures!” is my first response. Instictively I guess that they won’t be around for long. And sure enough, by the time I make it home, there are just a few bees hanging around the branch.
That’ll teach me to leave the property!!
Luckily, Phil got some good documentation of the incident.

My father theorized that the bees were splitting the colony. Research backs him entirely. It seems that this is the method of colony reproduction.
The University of Nebraska answered a lot of my questions:
What makes a honey bee colony swarm?
Overcrowding and congestion in the nest are factors which predispose colonies to swarm. The presence of an old queen and a mild winter also contribute to the development of the swarming impulse. Swarming can be controlled by a skilled beekeeper; however, not all colonies live in hives and have a human caretaker.
When do honey bees swarm?
The tendency to swarm is usually greatest when bees increase their population rapidly in late spring and early summer. [May and June]
Iowa State University offers this information:
Honey bee swarms may contain several hundred to several thousand worker bees, a few drones and one queen. Swarming bees fly around briefly and then cluster on a tree limb, shrub or other object. Clusters usually remain stationary for an hour to a few days, depending on weather and the time needed to find a new nest site by scouting bees. When a suitable location for the new colony, such as a hollow tree, is found the cluster breaks up and flies to it.
All sources stated that swarming bees are not dangerous, for a couple of reasons. One is that while they’re swarming, the bees don’t have a home that they feel like defending. Also, while swarming they don’t have any access to food stores, so they eat right before leaving, thus their ability to sting is reduced.
Since our bees moved on in a couple of hours (or less!) I assume the scout bees found a suitable location for the new colony, but I don’t know where that is. And there are still bees in the Big Tree.
