This insect has a wider range of colors and spot numbers than other lady beetle species. Wings range from black to mustard; spots number zero to many. The most common U.S. form is mustard to red with 16 or more black spots.
Lady beetles that enter wall spaces in the fall may remain there, without entering living areas, until they depart in spring to search for food. But some may become active on warm days in late winter or early spring and move into living areas.
