The majority of coccinellid species are generally considered useful insects, because many species prey on herbivorous homopterans 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 explosively in years when their natural enemies, such as parasitoid wasps that attack their eggs, are few. In such situations, they can do major crop damage. They occur in practically all the major crop-producing regions of temperate and tropical countries.
