How to recognize oleander scale 

The cover of female oleander scales is almost round and translucent white with a yellow tip in the middle. The cover of male oleander scales has the same color, but is smaller and more elongated. Males only live for a few days. The first stage (crawlers) are yellow and can be spread by wind. They will attach to a plant and form cover, after which they become immobile. In one to two months it will develop into an adult female.

Oleander scale damage 

Oleander scale can be found around the world and uses important crops, like olive and citrus, as host. The scales are usually found in clusters on the underside of the leaf. During feeding, toxic substances are injected, which cause yellow spots. Deformation of shoots is common. Heavy infestation leads to withering of leaves and stems, which can cause death of the plants.
