RECOGNITION
Adults have bare humeri (postpronotal lobes), though these are often hidden by the concave posterior of their close fitting heads. Larvae have pairs of locomotory organs on the first six abdominal segments. These are not true prolegs because they lack musculature and crochets.

BIOLOGY
Food
Adult: Adults exploit pollen and nectar produced by native plants having large inflorescences and flat corollae (e.g. Apiaceae, Asteraceae, Ranunculaceae and Rosaceae). Larva: The larvae are primarily aphid predators. Some are generalists, others specialize in just a few species of aphids. Those in the Pipizini tribe specialize on gall forming aphids.
Importance
Efficient biocontrol agents and minor pollinators.
