It’s the annual attack of the tiny, very hungry winter moth caterpillars. Over the past few days, the green inchworm caterpillars have begun ballooning down out of trees by the thousands, dangling on a wisp of thread and leaving behind a tattered, frayed canopy of leaves.
“There’s a tattering of the leaves. A lot of this comes from the caterpillars feeding on the buds before they open,” said Joseph Elkinton, a professor of entomology at the University of Massachusetts Amherst who has for a decade been releasing a parasitic fly that has begun to have success in controlling the population of hungry caterpillars.
