Natural Habitat

Gardens, forests, crops, parks, and buildings; common on foliage with aphid colonies. Native to East Asia and widely introduced elsewhere.

Diet & Feeding

Adults and larvae primarily eat aphids, scale insects, and other soft-bodied arthropods; they may also consume mites, insect eggs, nectar, and fruit.

Behavior Patterns

Adults are active predators and aggregate in large numbers to overwinter, often inside buildings. Color and spotting vary greatly; larvae are dark, segmented, and spiny.

Risks & Benefits

Beneficial biological-control predator of crop pests. It can bite or release a yellow, odorous defensive fluid, become a nuisance indoors, and occasionally trigger allergies.
