Coccinellidae () is a widespread family of small beetles ranging in size from 0. 8 to 18 mm (0. 03 to 0. 71 in). The family is commonly known as ladybugs in North America and ladybirds in Great Britain and other parts of the English-speaking world. Entomologists prefer the names ladybird beetles or lady beetles as these insects are not classified as true bugs. The majority of coccinellid species are generally considered beneficial insects, because many species prey on herbivorous hemipterans such as aphids or scale insects, which are agricultural pests. Many coccinellids lay their eggs directly in aphid and scale insect colonies in order to ensure their larvae have an immediate food source. However, some species do have unwelcome effects, among these, the most prominent are of the subfamily Epilachninae (which includes the Mexican bean beetle), which are herbivorous themselves. Usually, epilachnines are only minor agricultural pests, eating the leaves of grain, potatoes, beans, and various other crops, but their numbers can increase exponentially in years when their natural enemies, such as parasitoid wasps that attack their eggs, are in fewer numbers. In such situations, they can do major crop damage. They occur in practically all the major crop-producing regions of temperate and tropical countries. Etymology The name coccinellids is derived from the Latin word coccineus meaning 'scarlet'. The name 'ladybird' originated in Britain where the insects became known as 'Our Lady's bird' or the Lady beetle.
