BioNB 221: Lecture 7 Sept. 12, 2008 Page 1 Lecture 7: Dance communication in honey bees Dr. Heather Mattila 1. Introduction Honey bees form spectacular colonies of thousands of related individuals; sterile female workers cooperate to rear the offspring—their worker sisters and drone brothers—of their mother, the queen. Their societies are large, bustling, and extremely energy demanding. For example, honey bees need to maintain a nest temperature of 35 ° C (~95 ° F) whenever they rear new members of the colony, which happens during much of the year (even in the winter). Consequently, to fuel their many activities, honey bees must stockpile vast amounts of their food (honey and pollen) during the short period of summer that these resources are available. To efficiently exploit ephemeral food resources in the environment, a complex system of communication has evolved in all honey bee species that allows workers to transfer information among nest mates about lucrative food discoveries. 2. Discovering the meaning of the bees dance Many famous thinkers, including Aristotle, pondered how honey bees coordinate rapid recruitment of nest mates to food finds. In the first half of the 20 th century, an Austrian researcher named Karl von Frisch performed a long series of experiments that systematically uncovered the meaning of the curious movements (see below) that many foragers make after returning to the nest from a foraging trip. In 1973, von Frisch was awarded the Nobel Prize for his work in the field of animal behavior, which included his enormous contribution to our understanding of the use of dance communication by honey bees. 3. How do honey bees communicate with each other?
