Ladybugs
The Coccinellidae are a family of small beetles, ranging from 0.8 to 18 mm (0.0315 to 0.708 inches).[3] 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,[4] more than 450 native to North America alone.
Coccinellidae are known colloquially as ladybirds (in Britain, Ireland, the Commonwealth, and the southern United States), ladybugs (originating in North America) or lady cows, among other names.[5] When they need to use a common name, entomologists widely prefer the names ladybird beetles or lady beetles[6] as these insects are not true bugs.
