Efferia argentifrons

Efferia argentifrons is a robber fly in the family Asilidae, first described by Hine in 1911. The species is characterized by its distinctive silvery facial markings, as indicated by its specific epithet ('argentifrons' = silver-faced). It belongs to a large genus of predatory flies known for their robust build and aggressive hunting behavior. Field observations of this species are sparse, with only three documented observations on iNaturalist, suggesting it may be uncommon or underreported.
