Description and Identification

Golden-backed Snipe Fly adults drink nectar and other plant juices. Their long legs allow them to easily walk along vegetation while feeding. Some species can deliver a mild bite to humans if handled, but this fly generally ignores people. The long, thin body also permits adept flying skills.
Unique Appearance
While many flies exhibit drab colors, the Golden-backed Snipe Fly is a true standout. The bright yellow thorax contrasts elegantly against the black body. This golden patch inspired the fly’s common name.
Up close, the orderly rows of rectangular white flecks on the abdomen almost resemble stitching on a finely tailored jacket. These markings look crisp and clean, lending a smart, geometric appearance.
The dark wings complement the light and dark elements on the body. The striking color scheme sets this fly apart with a modern style all its own in the insect fashion world.
With its vibrant yet refined black, yellow, and white palette, the Golden-backed Snipe Fly brings artful beauty to the fly world. This unusual color pattern likely protects the fly while also attracting mates. Next time you are in the eastern woodlands, keep watch for these exquisitely-marked insects dancing through the dappled forest light. The Golden-backed Snipe Fly reminds us that nature contains boundless treasures for those who pay close attention.
