Yes, it’s the emerald ash borer, that infamous pest from Asia, whose larval feeding tunnels can girdle the inner bark of an ash tree, cutting off its supply of nutrients and water and eventually starving the tree to death.

The adult emerald ash borer (EAB), as its name suggests, is a bright, iridescent green beetle, about ⅓ inch long. It has a coppery-red upper abdomen that is often hidden under its wings.

Although the adult EAB does chew on the leaves of ash trees, this is not the primary source of trouble. Rather, the female EAB, which lives for about six weeks, can lay anywhere from 40 to 200 eggs in the tree’s bark. Fertilized eggs hatch about two weeks later, after which the larvae chew tunnels through the outer bark and into the inner bark. This is the real source of trouble for the tree because those serpentine tunnels ….”
