Mating Flight

At approximately 3pm a swarm like group of bees took to the air. However the size of the swarm looked smaller than usual and less organized. The swarm did not go very far or very high in the air. The swarm landed on a hive stand just 20 feet away. I assume this was a mating flight. The ball of bees was very small and I could not find a queen. The bees went into the cardboard box and then the box was placed back at the mother hive where they all returned.
