Habitat and pests eaten 4
C. stigma mainly lives within terrestrial/arboreal habitats, primarily feeding on aphids found in these habitats as well as scales (such as pine needle scale, beech bark scale and Florida red scale) and mealybugs. It is a beneficial insect, and is useful in both natural wood stands and commercial forests such as orchards and citrusgroves. It is beneficial against non native species. An introduced Hemlock pest, the elongate hemlock scale (Fiorinia externa Ferris), which has been doing considerable damage to Hemlock trees throughout North America, can be moderately controlled by the presence of C. stigma. C. stigma is currently not a lady beetle that can be sold for commercial use in orchards or on farms.
