The 22-spot ladybird is a small ladybird found in a wide range of habitats, particularly grassland, woodland edges, towns and gardens. It feeds on mildew (fungus) on a variety of plants. The lifecycle of a ladybird consists of four phases: the egg; the larval stage, during which the larva undergoes a series of moults; the pupa, in which the larva develops into an adult; and the adult phase, during which the female lays eggs in batches of up to 40.
