Chrysops relictus is a medium-sized horse fly with a body length of 8-10.5 mm.
It has a pair of diverging twin black lobes on the second abdominal tergite, uniting at the base to form an inverted yellow V mark.
This distinguishes Chrysops relictus from the similar looking Chrysops viduatus, which has a single quadrate spot of variable size.
The clear area near the anal margin of wing is suffused with black, creating a clear spot.
