The white egg bag grows two to three times longer than the bug itself and holds hundreds of red eggs.
The babies spread by crawling and by blowing away in the wind.
Many scale insects lose their legs as they grow up, but this one keeps its legs all its life.
In 1888 a ladybird was brought from Australia to California to eat it. The ladybird saved the orange farms there.
Almost all of them are both mother and father at once. Real males are rare.
