Adult Mealybug Destroyers look like spotless black lady beetles that have brown heads. If these adults are present in your garden, they are doing your plants a great service. This species was deliberately imported from Australia in 1892 to help control mealybug infestations in California citrus groves. Mealybugs are cottony looking insects that suck a plant's juices, weakening them, possibly to death. Their abundance was having an economic impact in the agricultural industry. The introduction of the Mealybug Destroyer was successful and these days it is bred and sold everywhere in North America.

The white larvae of the Mealybug Destroyer are more conspicuous than adults. They are sometimes mistaken for Mealybugs themselves because of the similarities in appearance. The tiny Mealybug Destroyer Larva has what almost look like curly tentacles or appendages extending from a dark body. The nefarious mealybug is almost white as well, but it has straight, stiff white white hairs projecting from its sides. Mealybugs can also grow long, thin tails; the beneficial Mealybug Destroyer larva does not. Young Mealybug Destroyers are extremely useful in aphid pest management as well as mealybug control. Learning to tell the two insects apart benefits both the gardener and the plant.

* MAP NOTES: The territorial heat map above showcases (in red) the states and territories of North America where the Mealybug Destroyer may be found (but is not limited to). This sort of data is useful when attempting to see concentrations of particular species across the continent as well as revealing possible migratory patterns over a species' given lifespan. Some insects are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America. States/Territories shown above are a general indicator of areas inhabited by the Mealybug Destroyer. Insects generally go where they please, typically driven by diet, environmental changes, and / or mating habits.
