Cryptolaemus montrouzieri, AKA the Mealybug Destroyer, and the name says it all. C.montrouzieri definitely prefer to eat mealybugs. They can clean up large populations in short order. As with most beetles, Cryptolaemus montrouzieri is very opportunistic and will eat other pests such as scale insects, IE: their crawling or immature forms, eggs, etc. We do not suggest using these beetles for other pests, though.
