Ladybugs (called ladybirds in some countries) are a family of beetles that includes the Asian Lady Beetle (Harmonia axyridis), among others. The Asian lady beetle has large white "cheeks" and a black "W" (or "M", depending upon how you look) on its head. Other ladybugs have a black head and, if they have white marks, they are not as large as the cheeks of the Asian lady beetle.
