The harlequin ladybird, Harmonia axyridis, is one of the world’s worst invasive insects. It can be distinguished from other ladybirds by the black ‘M’ or ‘W’ on its neck. The number of black spots on its body can vary from 0 to 20, and it can range in colour from light orange to dark red. It is between 0.5 and 1 cm in size. (Photo credit: Ingrid A. Minnaar)
