The elm leaf beetle ( Xanthogaleruca luteola ) (Muller) was accidentally introduced into the Eastern U. S. early in the nineteenth century. It feeds on all varieties of elm trees, especially Siberian and European elms. However, feeding damage is much less evident in varieties such as cedar elm, lacebark elm, American elm, and winged elm. Damage to these varieties may be more severe if other elm trees that the beetles prefer are unavailable. The elm leaf beetle is also known to cause some damage to Japanese zelkova. (2 Pages)
