Harmonia axyridis

Harmonia axyridis is a large lady beetle or ladybird species that is most commonly known as the harlequin, Asian, or multicoloured Asian lady beetle. This is one of the most variable lady beetle species in the world, with an exceptionally wide range of colour forms.^[2] It is native to eastern Asia, and has been artificially introduced to North America and Europe to control aphids and scale insects. It is now common, well known, and spreading in those regions, and has also established in Africa and widely across South America. This species is conspicuous in North America, where it may locally be known as the Halloween beetle, as it often invades homes during October to overwinter.^[3] Other names include multivariate, southern, Japanese, and pumpkin ladybird.^[4]
