- Figure: FG31-18 Title: Honeybee society. Caption: Out of thousands of females in a honeybee colony, only one bee, the queen, is likely to bear offspring. Each colony is composed of numerous female worker bees, a small number of male drones—whose sole function is to mate with a queen—and the queen bee herself. Shown is a group of workers surrounding a queen in a North American hive.
- Figure: FG31-19 Title: Fire ant society. Caption: Like honeybees, fire ants live in societies that are organized around the care of the one breeding female, the queen, and the eggs she lays.
