Chilocorus stigma
In 3 days ~20% in a week ~40%
Chilocorus stigma, commonly known as the twice-stabbed ladybug, is a native resident of the United States and Canada. It also has been introduced to Hawaii. It is shiny black, and there is one red spot on each elytron. The remainder of the body is black as well, but the abdomen is either yellow or red. It is sometimes confused with the "two-stabbed lady beetle", Chilocorus orbus, which is widespread in California.
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 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. C. stigma is currently not a lady beetle that can be sold for commercial use in orchards or on farms.

GBIF citizen-science records
It is estimated from how often the Twice-Stabbed Lady Beetle is recorded against all the insects logged in Point Pelee National Park (5 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
