Saropogon
robber flies, assassin flies
Saropogon is a genus of predatory robber flies (Asilidae) comprising at least 128 described species globally. The genus is distinguished by a stout, often twisted spur at the antero-ventral apex of the fore tibiae, open cell m3 on the wing, and an antennal stylus with a single element. Nearctic species north of Mexico include 19 recognized species, with many exhibiting pronounced sexual dimorphism in coloration and wing patterns. Adults are venomous aerial predators that immobilize prey through extra-oral digestion initiated by injected venom.
