Abstract
"Throughout much of the country, the multicolored Asian lady beetle (Harmonia axyridis) has become an unwanted houseguest, especially during the spring and fall months. Adult individuals can be quite diverse in size, color, and spotting. They are usually about one-quarter inch long, oval in shape and about four-fifths as wide as they are long. The color of the wing covers (the domelike shell over most of the body) can range from beige to yellow to yellowish orange to bright reddish orange; a few individuals may even appear mostly black. They are adorned with anywhere from Oto 21 black spots, but 19 is most commonly seen (Figure 1 ). The area just behind the head and in front of the wing covers is white with a black M-shaped mark. From 1916 to the late 1970s, scientists attempted to introduce this species to agricultural areas throughout the United States and Canada because of its great value as a biological control agent. The first individuals were found in Missouri in 1979. The Asian lady beetle is a very beneficial insect during the growing season because both the larval and adult stages feed on aphids, mealybugs, scale and other soft-bodied insects that infest many important crops and plants." -- first page
