Elm Leaf Beetle

Found primarily on and around elm trees in urban, suburban, and forest environments.

Herbivorous; both larvae and adults feed exclusively on the leaves of elm trees (Ulmus species), skeletonizing the foliage.

Adults overwinter in protected areas like house attics or under bark. They emerge in spring to lay yellow eggs on the underside of leaves. They are known for their ability to fly and locate host trees.

No health risk to humans. However, they are significant pests to elm trees, causing aesthetic damage and weakening trees through repeated defoliation.
