Robber fly - Efferia aestuans - Watertown, Middlesex County, Massachusetts, USA July 4, 2017 Size: about 20 mm
Robberfly sitting on Trumpet Honeysuckle (Lonicera sempervirens) waiting to ambush. The asymmetrical hexagonal faceting on eyes really nice. Not sure if faceting is an internal (light effect showing interior eye structure) or external feature. Always fascinated by the architecture of insects revealed through magnification.
