PHOTO COMMENT
BugGuide
These beetles are flatter and more elongate than adults of other Lady Beetles. They overwinter in masses in Joaquin Miller Park and other hilly areas. Convergences ofthese beetles make it easy for nurseries to harvest them for sale to farmers and gardeners for biocontrol of plant pests. Wing cover color varies from orange to dark red, and may even be a dull green-gray.

Description
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.

BIOLOGY
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.
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.
