Chilocorus stigma
''Chilocorus stigma'', commonly known as the twice-stabbed lady beetle, is a native resident of the United States and Canada but does not live west of the Sierra Nevada. The two-stabbed lady beetle ''Chilocorus orbus'' is found widespread in California.〔 p. 299〕 It also lives in Oceania and has been introduced to Hawaii. It is shiny black in color, and there is one red spot on each elytra. The remainder of the body is black as well, but the abdomen is either yellow or red in color.
== Habitat and pests eaten ==
''C. stigma'' mainly lives within terrestrial/arboreal habitats, primarily feeding of 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 citrus groves. 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''.〔(【引用サイトリンク】title=Elongate hemlock scale )〕 ''C. stigma'' is currently not a lady beetle that can be sold for commercial use in orchards or on farms.
