This image of an Asian lady beetle sitting on a grape leaf was taken in Portland, Oregon. According to the Wikipedia page they are "native to eastern Asia from central Siberia, Kazakhstan and Uzbekistan in the west, through Russia south to the Himalayas and east to the Pacific coast and Japan, including Korea, Mongolia, China and Taiwan." They have been introduced in other areas of the world such as South America and Africa and are considered a threat to native species in these areas. In North America they help with aphid control.
Adults are 6 mm in lenth. The body is ovate with a dark orange to red color. The number of spots vary in numbers and can be identified by a "m" or "w" - shaped marking on the backs of their heads.
