The European elm flea weevil (Orchestes alni) has been a pest on elms in the upper Midwest only since 2003, though it was first discovered in the U.S. in 1982. It is especially common on Siberian elms. The insects are tiny weevils about 1/16th of an inch long with long snouts. They are reddish brown with black heads and have black spots on their wing covers. Their hind legs are thickened and useful for jumping. They fly when disturbed.
