Ribbons fluttering from trees will mark the fourth annual emerald ash borer awareness week in New York State.
The state Department of Environmental Conservation says the awareness week runs from May 18 until the 24th.
The emerald ash borer is a beetle native to China that kills ash trees. It was first spotted in North America in Michigan in 2002 and has since spread to 22 states and the Canadian province of Quebec. It has spread across New York since it was first reported in the southwestern corner of the state in 2008.
The beetle's larvae have destroyed tens of millions of ash trees in the U.S. since 2002.
Volunteers will tie ribbons on more than 6,000 ash trees to raise awareness of the insect.
