The United States Department of Agriculture (USDA) is asking people to make time in the month of August to check their trees for an invasive beetle. The USDA says they have lost more than 180,000 trees across New York and Ohio to the Asian longhorned beetle. The invasive insect feeds on hardwood trees like maple and birch, as well as elm and ash trees. In Ohio, the beetle is confined to Clermont County, east of Cincinnati. Although the species moves slow, it can have devastating effects on the ecosystems it enters.
