Section I: Recognition and Identification of Phlebotomine Sand Flies
Is it a female of genus Phlebotomus or Sergentomyia?
Unless you slide mount the specimens, the best way to separate female Phlebotomus from Sergentomyia is to observe the wing shape with a dissecting microscope.
Phlebotomus sergenti wing. Phlebotomus wings are broader and asymmetrical, top to bottom.
Sergentomyia bedfordi wing. Sergentomyia have narrow, lanceolate wings. (Imagine that if you folded the wing in half from top to bottom the two halves would fit perfectly on top of each other).
