Identification
Adults are slightly elongated in shape, from 4-7 mm in length. Prominent black and white pattern behind the head, and black spots on red forewings. They may have a full complement of 13 spots or only a few. The white lines that converge behind the head are common to all individuals.
Range
Common and widespread in North America, thanks in part to commercial sales for biological control. Ranges to South America (Hoffmann and Frodsham 1993, White 1983). - University of Michigan Museum of Zoology
Life Cycle
They can adjust their life cycle according to the availability of aphids. Resident populations in the eastern United States are active throughout spring and summer if aphids are present.
