Let us begin not with the who, which was several thousand bees and a bunch of people in anti-sting gear that looked like spacesuits, or the what, which was harvesting honey. Let us go directly to the where.

It was not a bosky setting that would bring to mind the Robert Frost poem about good fences and good neighbors, but the south roof of the Jacob K. Javits Convention Center on Manhattan’s Far West Side. Here the neighbors are the unfinished towers of the Hudson Yards development. They ring what has become an urban meadow — the south roof, mostly covered by 6.75 acres of kaleidoscopic sedum. It is yellowish green. It will turn red in time for Christmas.

The bees have been in residence since spring. The first 12,000 came from California, transplanted in a three-pound container that looked like a shoe box with screens on both sides. They were placed in wooden hives, which look like stackable drawers. There were 60,000 to 80,000 by midsummer.

The accommodations are typical of urban apiaries. Liane Newton, the director of nycbeekeeping.org, who tends them, described her role as “convincing them they live in a tree trunk when they live in a file cabinet.”
