EtymologyÉtienne Mulsant described C. montrouzieri, naming the new species after a Marist brother and missionary, Abbe Montrouzier, who wrote an "Insect Fauna of Woodlark Island".[2]DistributionCryptolaemus montrouzieri is endemic to Queensland and New South Wales, Australia. It is also present in southern Europe (France, Italy, Spain, Greece), in the Afrotropical realm, in the Nearctic ecozone, in the Neotropical ecozone and in North Africa.[3][4]DescriptionCryptolaemus montrouzieri can reach a length of about {{convert|6|mm}}. Adults of this species have the typical ladybird shape but, unlike many of the often brightly coloured Coccinellidae, the elytra of these small ladybirds are predominantly dark brown and have no spots. Head, antennae, pronotum, the end of the elytra and the legs are orange-brown.[5] Larvae can reach a length of {{convert|14|-|15|mm}}. They show a waxy covering that makes them apparently look like the mealybugs they prey on,[7] a case of aggressive mimicry. BiologyThe adults and larvae of these insects eat scale insects, especially mealybugs. Females lay their eggs among the egg sack of mealybugs. Larvae feed on mealybug eggs, young crawlers and their honeydew. They become adults in 24 days, after three larval stages and a pupal stage. The life span lasts two months.[8][6] Biological control agentThis species has been used as a biological control agent against mealybugs and other scale insects.[2][5] It was introduced to Western Australia.[2] In California it has been introduced in 1891 by Albert Koebele to control the citrus mealybug.[5] It has also been introduced to New Zealand for biocontrol.[7] As biological control agent outside Australia, C. montrouzieri has the common name Mealy bug destroyer.[5][8] See also
