A good bug with some bad habits
The multi-colored Asian lady beetle is a native of Asia, and like many exotic species, has readily adapted to climates and habitats in the U.S. As with most lady beetles, it is a highly beneficial predator of insect pests, especially aphids. Asian lady beetles can create trouble when large numbers enter buildings or feed on late season fruit crops.
