Diet & Feeding

Primarily carnivorous, feeding on aphids, scale insects, and other soft-bodied agricultural pests.

Behavior Patterns

Risks & Benefits

Benefits the ecosystem by controlling aphid populations. However, they are considered a nuisance pest when they enter homes, can cause minor allergic reactions in some humans, and may occasionally nip at skin.
