Elm Leaf Beetle

The Return of the Elm Leaf Beetle?

A site visit last week revealed a heavy infestation of Elm Leaf Beetle on ‘Patriot’ elm street trees in downtown Cincinnati. It was a surprise. This non-native beetle was once considered a major urban forest pest in Ohio as well as across most of the U.S. and eastern Canada. However, for unknown reasons, the beetles seemed to vanish from much of the U.S. in the early 1990s.
