Harmonia axyridis is a 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. 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. Other names include multivariate, southern, Japanese, and pumpkin ladybird. Like other coccinellid beetles, this species may interchangeably be referred to as a lady beetle, ladybug, or ladybird, though entomologists prefer the names ladybird beetles or lady beetles to avoid confusion with true bugs. A widespread misconception exists that this species is not a ladybug due to confusion over common names.

GBIF citizen-science records
It is estimated from how often the Asian Lady Beetle is recorded against all the insects logged in Great Smoky Mountains National Park (372 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
