To many, the Asian Lady Beetle is the classic “ladybug”. Its coloration is most often red or orange, and it can have 0-22 black spots. This species is native to Asia, however it is now found throughout much of North America and in parts of Europe. In the cooler months, Asian Lady Beetles go dormant. You will often find them congregating in warm spots in your house or other buildings. Although ferocious predators of agricultural pests, they have likely played a significant role in the disappearance of many native Lady Beetle species.

Fun Fact

Asian Lady Beetles have a surprising number of names — so many in fact that the UK nick-named it the “many-named ladybird”. Some of these names include: harlequin, southern, Japanese, and pumpkin lady beetle.


The Asian Lady Beetle is between 4 and 7 mm in length, and is oval in shape. This beetle exhibits high morphological variation, with both the elytra and the pronotum varying greatly in appearance from individual to individual.


Habitat generalist. Can be found in fields, meadows, forests (deciduous and coniferous), orchards, on agricultural crops, in disturbed areas, and in houses (especially during the winter). Prefers arboreal habitats in native range.

General Range

Native to Asia, spread across the U.S and parts of Canada.


Primarily aphids, with a preference tree-dwelling aphids, psyllids, and scale insects. They will also consume pollen, fruit, and other lady beetle larvae, which is thought to be a contributing factor to the decline of several native lady beetle species.

Life Cycle

Usually incubates as an egg for around 3 days, goes through larval stages for around 10 days, and then pupates for 5 days. Adults can live anywhere from a month to 3 years, but typically live from 1 to 3 months.
