Dawn Of The Lanternfly

A bizarre invasive pest from Asia is spreading fast and putting billions of dollars’ worth of resources at risk

From the road heading east, the apple trees of Beekman Orchards unfold in waves, rising and falling on a sea of verdant grass. Behind them, basking in the June sunlight, are row upon row of pinot noir, Riesling, and Traminette grapes. It’s for the vineyard that I’ve driven to this 170-acre estate in Berks County, an hour and a half northwest of Philadelphia. Beekman Orchards is a fourth-generation family enterprise, now carefully stewarded by Calvin Beekman, a large 59-year-old man with a calm voice and meat-hook hands.

“I told one fella one time I don’t need to go to Atlantic City, because we’re the biggest gamblers there are,” he tells me outside his farmhouse. In 1999, Beekman planted the vineyard, 40 acres of red and white grapes that once brought in about a quarter-million dollars annually. On this day, several rows of vines in the middle of the patch are a lush green, close to the fruit-set stage. Mid-June is usually when clusters of grapes bloom, growing until harvest begins in mid-September. In the rows farther out, though, no clusters are visible, and the grape-shoot trunks are blackened, dead. Beekman gestures toward a set of Riesling vines that went in just last year. “This row contains 140 plants,” he says. “I don’t think you can find one percent that’s viable.”

A third of his vineyard has suffered a similar fate. Another third is struggling. And the luxuriant middle third? It could be at risk, too. He points to the woodlands surrounding his farm and utters a word that’s been unnerving farmers, foresters, public officials, and entomologists alike: “lanternflies.”
