Family Coccidae (Scale insects)

Most of the endemic Australian scale species cause little damage to their host plants.  Some of the introduced species however can cause significant damage to crops.  Often crop loss is due to the honeydew that is secreted by the scale that a black sooty mould then grows on.  This affects the ability to sell the fruit.
