Abstract

History, identification, and indoor and outdoor control of the elm leaf beetle are discussed.

The elm leaf beetle is an imported pest, first found in the United States in 1834. Common throughout Nebraska, it is almost exclusively a pest of elms, including the American, Siberian and other varieties. Japanese Zelkova is also readily attacked. Adults (beetles) vary in color from yellow to olive green, and have a black stripe near the outside of each wing cover. They can be confused with other beetles of similar appearance (western corn rootworm, striped cucumber beetle), but they are distinctive in that they occur early in the season and have three dark spots on the body segment behind the head.
