Homepage / Checklist of families
Chamaemyiidae is a widespread family comprised of about 100 species of acalypterate flies whose free-living and predaceous larvae are often used as biological control agents of aphids, coccids, and scale insects. Adults of living forms are known to feed on sap. Only one fossil species in the extinct genus Procremifania Hennig has been described from Eocene/Oligocene Baltic amber. In addition to this species, undetermined material of the family has also been recorded from the Oligocene/ Miocene amber of the Dominican Republic (Poinar, 1992).
