First described in 1850 by Étienne Mulsant
Three introduced species in North America:
, Multicolored Asian Lady Beetle
, Cream-streaked Lady Beetle
Harmonia axyridis: Pattern and color of elytra (wing covers) is highly variable; see species Info page for more information. Usually orange or red with black markings, but may be orange or red with no markings, or black with red markings. Head and pronotum always black with white markings.
Harmonia dimidiata: Elytra orange or red with black spots, less variable than H. axyridis. Head and pronotum with orange markings, not white.
Native to Asia; introduced world-wide. In North America, H. axyridis is widely distributed, while H. dimidiata is limited to Florida. H. quadripunctata may be established in eastern Canada and the mid-Atlantic U.S.
Anywhere with suitable food, from ground level to treetops. Commonly seen in gardens, fields, and agricultural areas; also found in cities.
Year-round in the South; in colder climates, adults may overwinter but are usually inactive.
Primarily aphids; will also consume other soft-bodied insects, larvae, and insect eggs. H. axyridis may feed on ripe fruit in the fall.
Masses of spindle-shaped orange eggs hatch into spiky-looking larvae. Mature larvae are black with orange markings, up to 12 mm long. These larvae pupate, and the adult beetle emerges 1-2 weeks later.
