While growing, the larvae change their
colour and display a grayish-blue with irregular yellowish

A case of good luck for ladybirds is that humans consider them as useful insects. Their larvae as well as the adult insects eat large amounts of aphids. A single ladybird larva can clear up to 600 of them. This turns even rationalists into sympathists and saves the ladybirds from prosecution, at least in Europe. In other parts of the world some ladybird species may occur as a pest. |
