It has been well said that "if insects would quit fighting among themselves, they would overwhelm all Vertebrate animals"; though sometimes long biological investigations are necessary to keep them fighting when we have upset the natural conditions; , moved them to a new environment away from their natural enemies. Thus Acacia plants brought from Australia introduced the Cottony Cushion Scale which soon spread to the great California orange and lemon groves, and entailed enormous losses. The fruit growers finally sent, at their own expense, an expert entomologist to study in Australia the native enemies of the Scale-insect. As a result some Ladybird.
