Harlequin Ladybird - Harmonia axyridis

The Harlequin ladybird originated in Japan and it was introduced to many countries around the world as a biological control to try and control aphids, they can also vary in colour and markings. The larvae of these ladybirds are black and orange and are about 1cm in length and they also feed on aphids and other insects, they have an elongated body shape and are mostly black or dark grey, the eggs are yellowish to orange and are laid in groups on leaves and they are difficult to distinguish from other eggs of other ladybirds. Many ladybirds including the Harlequin overwinter in groups inside buildings usually in large groups and they are not a problem to people but they can exude a clear yellow liquid which may cause some staining to furnishings, they also over winter in cracks within barks or rocks and any crevice they find.
