Robber Fly with prey

Male Efferia sp. Found at Carr Canyon in Huachuca Mountains. Cochise County, Arizona, USA.

 

This robber seems to be missing some antennal segments on one side. Wonder if it is due to prey struggles at some point in its life.

 

Single exposure, uncropped, handheld, in situ. Canon MT-24EX flash unit, Ian McConnachie diffuser.
