features

The dead fly reaches a body length of 7 to 18 millimeters. Their body is large, elongated and has a metallic blue-green sheen. Seen from above, her abdomen is pointed trapezoidal. The face is noticeably elongated forward. In the male, a pair of frontal bristles, the vertex and the back of the head are darkened, the rest of the head and the palps are bright orange-yellow. The antennae are dark brown, their third link is partly darkened. The antenna bristle (Arista) is long hairy on both sides. On the sixth tergite they are densely hairy. The seventh tergite is only one third the width of the fifth tergite. The lower half of the forehead welt is brown in the female. On the mesonotum there is a pair of acrostichal bristles behind the seam. On the fifth tergite they have a dense row of long bristles. The similar Cynomya cadaverina has two pairs of acrostichal bristles behind the seam on the mesonotum, and the males also lack the frontal bristles.
