They are oddly shaped and mostly immobile. These appear as clusters of tiny bumps and usually won't be noticed until the damage is done. Scale can be armored or soft bodied. Armored secrete protective shell around themselves. They live and feed within that shell. Soft bodied secrete a waxy film (honeydew) attached to their bodies in very large amounts. They are flat spherical shaped. Damage will include yellow leaves, reduced vigor and poor growth. Natural predators of scale are lady bugs and lacewing, but only of young larva.
