A focus on bees as pollinators, as well as on honey bees, explores the basic biology of these essential creatures. Come to Berkshire Botanical Garden, 5 West Stockbridge Road in Stockbridge on Saturday, February 25 from 10 – noon to hear an absorbing presentation on the subject. $10 for BBG members, $15 for nonmembers.

Dr. Heather Mattila of Wellesley College shares information that allows beekeeper and naturalists to better understand the bees they see on flowers, how they live, and what they need in terms of habitat and food sources. To register, visit www.berkshirebotanical.org.
