Habitat: Urban, suburban and rural forests.
Diet: Adults feed on the foliage of ash trees, while the larvae tunnel and feed on the underside of the bark and cut off the transportation of nutrients and water to the tree.
Native Range: Eastern Russia, Japan, Northern China and Korea.
Local Concern: Since the first discovery in Michigan in 2002, this invasive beetle has killed tens of millions of ash trees in Michigan, both in forests and in neighborhoods. Adults typically only fly about ½ mile. On their own, this species doesn’t spread very far. The real concern with spread is the relocation of infested firewood to non-infested areas. Don’t move firewood!
Means of Introduction: The emerald ash borer most likely arrived in the United States via solid wood packing materials arriving from Asia.
