The hemlock woolly adelgid hails from Osaka, Japan. When it moved to the US in the 1950s, it settled right in, facing no natural predators and feeding off the buffet of hemlock forests lining the eastern coast. Similarly, the gypsy moth, a European emigre, now gobbles up the leaves of millions of acres of trees (pdf, p.5) each year. And the emerald ash borer, a beetle of Eurasian extraction, has killed millions of trees in North America in just over a decade, earning it the title of “worst forest problem in our lifetime” from a Colorado State University entomologist.
