Robber Fly (Efferia sp.)
While mostly harmless to humans (they might bite is self-preservation), robber flies are fierce ambush predators that wait perch patiently for a flying insect to fly by, then launch into the air, overpower then dispatch their prey mid-flight. They hunt grasshoppers, bees, wasps, butterflies and even other flies! This one was found hunting in the Oak Creek State Wildlife Area, just outside of Yakima, Washington on a hot, late-spring day.
