The Coccinellidae (/ˌkɒksɪˈnɛlɪdaɪ/) are a family of small beetles, ranging from 0.8 to 18 mm (0.0315 to 0.708 inches). They are commonly yellow, orange, or scarlet with small black spots on their wing covers, with black legs, heads and antennae. Such colour patterns vary greatly, however; for example, a minority of species, such as Vibidia duodecimguttata, a twelve-spotted species, have whitish spots on a brown background. Coccinellids are found worldwide, with over 5,000 species described.
