Moth Invasion Spreads

Light Brown Apple Moth Threatens Wine Grapes, Other Crops It's rare that an environmental disaster unfolds at a pace that allows an audience to watch. But the invasion of the light brown apple moth is an example. The Australian moth with the sweet-sounding name was first seen in the United States this spring, and officials have been unable to contain it, as it has spread from county-to-county, even showing up once in the famed Napa Valley. That's a serious problem, and one that hits home to any connoisseur, because the moth is voracious. Grapes are far from the only crop threatened by this little insect.
