Euonymus Scale is yellow or whitish spots that appear on leaves. Males are narrow white and females are larger brown scales. Females spend the winter on the plant and lay their eggs in the spring. Young scales called crawlers, settle on leaves and twigs or are blown to other susceptible plants. The young suck sap from the plant. Plants infested may drop most leaves by midsummer. Branches often die and heavy infestations may kill the plant. Euonymus scale can be controlled w/ a systemic insecticide
