Silver Hammertail
Efferia tricella is a species of robber fly in the family Asilidae, commonly known as the Silver Hammertail. Robber flies in the genus Efferia are predatory insects known for their robust build, large eyes, and aggressive hunting behavior. The species was described by Bromley in 1951. Like other Asilidae, it is presumed to be an aerial predator that captures other insects in flight.
