Elm Leaf Beetle

Found wherever elm trees are present, including urban forests, gardens, and woodland areas.

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

Adults emerge in spring to feed and lay eggs on the underside of leaves; they often seek shelter in homes during winter (overwintering).

A significant agricultural/garden pest that can defoliate and weaken elm trees; considered a nuisance when they enter homes in large numbers.
