n.
or ladybird beetle
Any of the approximately 5,000 widely distributed beetle s of the family Coccinellidae.
The name originated in the Middle Ages, when the beetle was dedicated to the Virgin Mary and called "beetle of Our Lady." Ladybugs are hemispheric and are usually 0.30.4 in. (810 mm) long. They have short legs and are usually brightly coloured with black, yellow, or reddish markings. Several generations are produced each summer. Ladybugs are often used to control such insect pests as aphid s, scale s, and mite s, which they eat. Several species of ladybugs feed on plants.
