Bees, 🐝, and more bees are buzzing atop the @harvardilab at @harvardhbs. Our two hives are thriving and the colonies are busy collecting nectar and pollen from the 19 various flower and plant species in the rooftop garden. Work on the Harvard Life Lab is underway in the background. 📷: @greenharvard #GreenRoof #LifeatHBS #Sustainability #GreenHarvard #honeybees #Harvard #bees 🌼🍯
