The boxelder bug ("Boisea trivittata") lays its eggs on all maples, but prefers this species, clustering the eggs in bark crevices. The rosy maple moth ("Dryocampa rubicunda") also lays its eggs on the leaves of maple trees, including "Acer negundo". The larvae feed on the leaves, and in very dense populations can cause defoliation.
