Asian lady beetle

Harmonia axyridis

Asian lady beetles are between 4.8 and 7.5 mm long. Their elytra, covering a pair of membranous wings, occur in different shades ranging from yellow, orange and red to black and have anywhere from 0 to 20 spots. In Canada, the most common form is orange with 19 black spots.

The pronotum, which covers the front of the thorax just behind the head, has two football-shaped pale eye spots.

Lady beetles


Members of this beetle family are recognized for their characteristic dome shape. Brightly coloured for the most part, lady beetles have black spots when their wing covers are yellow, orange or red, and yellow or orange spots when their wings are black. The short antennae have little knobs on the end.

Lady beetle larvae are usually elongate and have brightly coloured spots or bands as well as spines and tubercles. Some larvae have been described as resembling tiny alligators.
