Tropidia scita


    Wing length: 5.5 to 8.25 mm

    The key identification feature of this hoverfly is the arched and swollen hind femur with a large triangular projection on its lower surface near the apex. (Visible is several photos below, including an enlargment.) The projection has small black spines along its hind edge.

    The abdomen has orange markings on tergites 2 and 3, covering the entire lateral margins in males, but reduced in females, sometimes to paired spots.
