A superb wasp mimic
Several Temonostoma species, like this one, mimic eumenine mason wasps. Note the darkened leading edge of the wing, to simulate the way mason wasps fold their wings longitudinally. Also, the flies wave their front legs in front of their face to simulate the long antennae of the wasp! This one appears to be simply cleaning itself.
