Pest description and damage The most visible stage of the cottony camellia scale is the adult female that resembles a flat 0.125-inch diameter scale often found on the underside of a leaf. Emerging from beneath the adult female is an oblong cottony white egg mass that can be up to twice the length of the adult scale. The cottony camellia scale (sometimes called taxus scale) crawlers are flat brownish or yellowish sucking insects. Foliage with scale infestations may turn yellowish or pale in color. Due to copious honeydew, leaves below are covered with a crust of black sooty mold. It is possible to have low numbers of this insect for years without an outbreak.
