Ladybird beetle adult (top) and larvae eating an aphid.

Adult ladybird beetles are well known aphid hunters. During development each ladybird beetle larva can consume hundreds of aphids or similar soft-bodied, sap-sucking garden pests.

Like green lacewings, ladybird beetles are commercially available for biological pest management. These predators however are more manageable in closed systems, like green-houses, rather than in outdoor applications.
