A green beetle blamed for destroying tens of millions of ash trees in 25 states is advancing in the St. Louis area.
The emerald ash borer found last year in trees at a St. Charles County industrial park now has turned up in the city of St. Louis.
The beetle slowly has marched south from Michigan and Canada, where it was discovered in 2002. Its larvae burrow into tree bark.
The executive director of the regional Great Rivers Greenway trails district, Susan Trautman, said there was no way to prevent the nuisance's local spread.
