Scale Insects, Soft Scales, Wax Scales 

Family Coccidae

This page contains pictures and information about Scale Insects in family Coccidae that we found in the Brisbane area, Queensland, Australia.
Two Scale Insects of different species 
The insects in this family are covered with wax secretion. The covering may be scale-like or mussel-shaped. From their appearance they do not look like insect. When they grow, most of their external organs, such as their legs, wings and antenna, are reduced and become functionless.
The young scale insects have three pair of legs, known as 'crawlers'. It is their responsibility for spreading and looking for suitable place to start new colony. They are very small, although they have no wings, they can spread by wind borne. When the females settle, they seldom move. Male adult scale insects are winged.

Pink Wax Scale insects affect different type of board leaf plants. The insects live under the protected shell cover which is their pink waxy secretion. The insects suck the juice from plants. Please check this page for more infromation.
