The gypsy moth has been a part of North American fauna since 1868, when it was imported from Europe and accidentally released in Massachusetts.
It has spread across the continent inexorably. In addition to Northeastern states, its range now includes parts of Ohio, California, Arkansas and probably half of Virginia’s counties.
The leaf-eating (defoliation) activities of gypsy moth larvae — and the associated disruption of forest ecology, economics and aesthetics — are problems Virginians have been dreading for a long time.
