Cryptolaemus montrouzieri, common name Mealybug Ladybird is ladybird species endemic to Queensland and New South Wales, Australia. Unlike many of the often brightly coloured Coccinellidae, it is predominantly brown and has no spots. It has been used as a biological control agent against Mealybugs and other Scale insects. As a larva it apparently looks like the mealybugs they prey on, a case of aggressive mimicry.
