On an organic farm in central New Jersey, the plants are vibrating with bees. With a swift twist of her insect net, Rachael Winfree captures a wild bee smaller than an adult human's little fingernail, without disturbing so much as a petal of the plant it was pollinating. She is standing over a patch of weeds between rows of upstanding garlic and sprawling watermelon vines, in a region that's part of the Stony Brook Watershed. It is high summer, hot and sunny. Perfect weather for bees.
