PolliNation was joined this week by Drs. Margaret Couvillon and Roger Schürch from Virginia Tech. As you will learn in this episode, the Couvillon Lab investigates the dynamics of how pollinators collect their food in the landscape, with a specific focus on honey bee foraging, recruitment, and health. Dr. Couvillon is in the Department of Entomology at Virginia Tech. Dr. Schürch is a Research Assistant Professor studying the Behavior, Ecology and Evolution of Insects. Over the last few years he has become increasingly interested in the honey bee waggle dance both as a tool for foraging ecologists, as well as from a basic science perspective. Today they talk about their collaborative work on using honey bee dance behavior as a way to assess habitat quality for bees.
Listen to today’s episode to find out what we can learn from bee dances, and how home gardeners can make a difference creating their own pollinator habitat.

“Let’s say you want to assess a large area for bee forage availability. If you are a traditional ecologist, you would walk transects and catalog the flowers you see, collect nectar and pollen samples to determine how much each flower is producing, and you have to account for competition. […] Even if you could do all that we calculated that it would take over 1,600 days to cover 90 km2. This is why we turned to the honey bee. The honey bee can do a lot of this hard work for us.” – Dr. Margaret Couvillon

“If you put an observation hive in a landscape and observe the duration of the honey bee dances, which translate into foraging distance, you will be able to say [whether a habitat is good or bad for the bees] at a given time.” – Dr. Roger Schürch
