February Featured Fact Sheet: Asian Lady Beetle

The multicolored Asian lady beetle, Harmonia axyridis, a native of Asia was introduced into the southeastern and southwestern portions of USA to deal with aphids on pecan trees. However, it spread rapidly to other portions of the US. It is a tree-dwelling lady beetle, more so than the native species of lady beetles, and a very efficient predator of aphids and scales. During the fall and early winter when the weather is cooler, the multicolored Asian lady beetle starts congregating on the south side of buildings and enters homes. The beetle does this because in their homeland of China they inhabit tall cliffs to overwinter. There are very few tall cliffs in Illinois, so the next best thing is a building.
