Hurt Plant

When woolly alder aphid feeds on its host plants, typically alder and silver maple trees, it primarily targets the leaves and roots. By sucking plant fluids, it deprives the plant of essential nutrients, leading to stunted growth and potential leaf deformation. The insect's activity also induces gall formation, which can further distort plant tissues, impeding their normal functions and affecting the overall health of the tree.
